Lester, the Lustre lister
by David Dillow
I'd like to announce the availability of Lester, the Lustre lister. It
is available from github at https://github.com/ORNL-TechInt/lester
Lester is an extension of (n)e2scan for generating lists of files (and
potentially their attributes) from a ext2/ext3/ext4/ldiskfs filesystem.
We primarily use it for generating a purge candidate list, but it is
also useful for generating a list of files affected by an OST outage or
providing a name for an inode.
For example, to list files that have not been accessed in two weeks and
put the output in ne2scan format in $OUTFILE:
touch -d 'now - 2 weeks' /tmp/flag
lester -A fslist -a before=/tmp/flag -o $OUTFILE $BLOCKDEV
To do the same thing, but generate a full listing of the filesystem in
parallel:
touch -d 'now - 2 weeks' /tmp/flag
lester -A fslist -a before=/tmp/flag -a genhit=$UNACCESSED_LIST
\
-o $FULL_LIST $BLOCKDEV
To name inodes to stdout (when not using Lustre 2.4's LINKEA):
lester -A namei -a $INODE1 -a $INODE2 ... $BLOCKDEV
To get a list of files with objects on OSTs 999 and 1000:
lester -A lsost -a 999 -a 1000 -o $OUTFILE $BLOCKDEV
To get a list of options and actions, use 'lester -h'; to get a list of
options for a given action, use 'lester -A $ACTION -a help'.
Lester uses its own AIO-based IO engine by default, which is usually
much faster than the default Unix engine for large filesystems on
high-performance devices. The number of requests in flight, request
size, cache size, and read-ahead settings for various phases of the scan
are all configurable. I recommend experimenting with the settings to
find a balance between speed and resource usage for your situation.
More information about the gains we've seen in testing prototype version
of Lester are in my LUG 2011 presentation,

lfs_migrate on an OST results in zero files inspite of being 60% used
by Kumar, Amit
Dear All,
I have yet another interesting thing happening and not able to understand.
One of the OST's that I want to migrate the data off of is 58% full and when I run the migrate script on the entire lustre file system, it only found few files migrated only couple of Gigs and now it does not find any files to migrate. Any idea how to interpret this? In the past when I was migrating an OST data it took a long long time because there literally millions of file to go through. Same is the situation here but every run of migration script just finished without moving anything anymore.
Any insight into this is greatly appreciated.
Best Regards,
Amit H. Kumar

How to locate the OST object through the MDT object for Lustre 2.5.0?
by Frank Yang
Hi all,
It seems I have little chance to successfully mount the lustre filesystem
again. As a result, I'm trying to extract the data back by inspecting the
MDT and OST objects on ldiskfs. However, I can only find an example of
"Identifying
To Which Lustre File an OST Object
Belongs<http://wiki.lustre.org/manual/LustreManual20_HTML/LustreOperations.html#5...>"
(
http://wiki.lustre.org/manual/LustreManual20_HTML/LustreOperations.html#5...).
That's exactly the opposite (OST->MDT) of what I want (MDT->OST). But, if
it could work, I could still make a big lookup table to get the data back
SLOWLY. However, it seems this example is for old Lustre.
Does anybody have some reference about this? I only use the default Lustre
2.5.0 configuration. It seems I need to check the oi.16 files to get the
correct mapping between MDT object and OST object.
I found a document
http://users.nccs.gov/~fwang2/papers/lustre_report.pdfdescribing the
internals of Lustre. However, I'm not sure if it's
up-to-date enough and actually I can hardly find enough time to comprehend
it. Below is a file map between OST and MDT objects that I'm sure of. If
somebody can help, it may be used as an example. Thanks a lot.

Retry for Lustre Server Move
by Frank Yang
Hi,
Sorry to write almost the same mail again. Since the original email with
tile "Help for Lustre Server Move" contains lengthy reports. I think
perhaps it's better to restart a new one.
I have restored Lustre from 2.4.2 back to 2.5.0. The error is basically the
same as the first mail I sent. However, I rearrange the commands and
outputs in order so that if somebody can help, he can have a better
understanding....
The case is basically the data move of the old MDS to another new MDS.

Is the MGS specification correct?

Re: [HPDD-discuss] Help for Lustre Server Move
by Frank Yang
I'm thinking perhaps I should change 2.4.2. back to 2.5.0. Originally I
"upgraded" 2.5.0 to 2.4.2 in the hope that it will fix the problem and
because it seems the database is compatible between these two versions. But
now, since it can't work, perhaps I should change it back to 2.5.0 again.
Does anybody have the idea of which one is better for later debug or
reconfiguration? Currently the old_mds is still 2.5.0 and it hasn't
"talked" to the 2.4.2 OSS since I haven't mounted it and haven't used
tunefs.lustre to change the mgsnode parameter back to old_mds on OSS.
new_mds is already 2.4.2.
BTW, does anybody know how to make a device which is in ATTACH state go to
the UP state. Perhaps it's a very important step in my case. Today I tried
to use "tunefs.lustre --erase-params /dev'..." and "tunefs.lustre
--writeconf /dev/...". The result now looks much more similar to the case
as mentioned in my first mail as below:
[root@old_mds ~]# cat /proc/fs/lustre/devices 0 UP osd-ldiskfs
lustre-MDT0000-osd lustre-MDT0000-osd_UUID 8
1 UP mgs MGS MGS 7
2 UP mgc MGC192.168.1.7@tcp 28fc524e-9128-4b16-adbf-df94972b556a 5
3 UP mds MDS MDS_uuid 3
4 UP lod lustre-MDT0000-mdtlov lustre-MDT0000-mdtlov_UUID 4
5 UP mdt lustre-MDT0000 lustre-MDT0000_UUID 7
6 UP mdd lustre-MDD0000 lustre-MDD0000_UUID 4
7 UP qmt lustre-QMT0000 lustre-QMT0000_UUID 4
8 UP lwp lustre-MDT0000-lwp-MDT0000 lustre-MDT0000-lwp-MDT0000_UUID 5
9 AT osp lustre-OST0000-osc-MDT0000 lustre-MDT0000-mdtlov_UUID 1
In my later experiment after the first email, I even couldn't see the OST
device (device 9 as above). Now, at least it comes back though still in the
AT state...
Actually I still don't understand why I can't restore them back. I have
chosen to completely destroy the configuration by "--erase-params" (only
"--writeconf" itself doesn't seem to destroy anything). This should enable
me to reconfigure them. So I guess there must be something more to destroy
or configure...
Regards,
Frank

Multiple independent MGSs/filesystems in a cluster
by Frank Yang
Hi all,
In the document, it's said MGS is universal in a cluster. But I want to
setup another MGS which is completely independent from the original one
since I am still trying to rescue the original one and don't want the
second one to make things more complicated. The reason why I need the
second one is because, before I successfully restore the original one, I
don't have enough space in a single RAID/machine. As a result, I need to
combine several smaller ones.
I guess by "universal MGS", it just means we don't need another MGS to
service multiple lustre filesystems. By if I don't care it, I can still
setup another MGS to service other lustre filesytems in my case. Can
anybody confirm this? Thanks a lot.
Regards,
Frank

Yes, we've noticed this also, and are looking at how to fix it.

I agree that the "new sparse look" seems a bit too sparse for me as well.
Even changing back to the "old interface" keeps the same grey-on-white
color scheme.
Joshua (who is on vacation over Christmas, so I don't expect a speedy
reply)
is there some option to change the color scheme so it is easier to separate
different parts of the interface?

Gerrit - Post upgrade
by Patrick Farrell
Good evening,
Since the upgrade to Gerrit, some links don't seem to work reliably. Sometimes I'll click a link from an LU, and most of the Gerrit page will load, but not the actual content, and it will give me the 'Working' message (I don't remember exactly what it says.). Reloading the page doesn't seem to help.
If I go to that page from a link not from Jira, like from one of the lists of proposed or merged patches in Gerrit, it seems to work fine. Has anyone else been seeing this? It's not crippling, but it makes looking at patches a bit annoying sometimes.
Next, and this is a bit more trivial, but at least to me, inconvenient:
The new 'grey text on all-white background' style is very hard to read. I much preferred the old, higher contrast color version, and there doesn't seem to be a user option to change it.
Perhaps some of those at Intel feel the same way and would be interested in getting it switched back to something higher contrast? Or perhaps I just have bad eyes. :)

Fwd: Help for Lustre Server Move
by Frank Yang
Hi all,
I previously setup a temporary combined MGS/MDS server and it worked fine
with the OST server and clients (Lustre 2.5.0). After I finished setting up
the final server, I used gnu tar v1.26 to "copy" the data from the
temporary one to the new one according to the lustre user manual. However,
then everything went wrong. The basic information:
*** Client (cola1)
eth0: 10.242.116.6
eth1: 192.168.1.6
modprobe.conf: options lnet networks=tcp0(eth1),tcp1(eth0)
*** Old MDS (cola4)
eth0: 10.242.116.7
eth1: 192.168.1.7
modprobe.conf: options lnet networks=tcp0(eth1),tcp1(eth0)
MGS/MDS mount point: /MDT
device: /dev/mapper/VolGroup00-LogVol03
*** New MDS (myoss)
eth0: 10.242.116.32
eth1: 192.168.1.32
modprobe.conf: options lnet networks=tcp0(eth1),tcp1(eth0)
MGS/MDS mount point: /MDT
device: /dev/sda6
*** OSS (new_mds)
eth0: 192.168.1.34
eth1: Disabled
modprobe.conf: options lnet ip2nets="tcp0 192.168.1.*"
OST mount point: /OST
device: /dev/sda5
*************************************************************************************
What I did (the steps are not so accurate enough since I have tried,
failed, and then retried according to what I google’d):

Is the MGS specification correct?
Is the filesystem name correct?
If upgrading, is the copied client log valid? (see upgrade docs)

During the tar, I accidentally created a file under /MDT then I deleted
it. Can this damage the MDT?
I even then tried to add failover nodes to OSS and run both MDS at the same
time, then try to “mount -t lustre 192.168.1.7@tcp:/lustre /lustre” and
“mount -t lustre 192.168.1.32@tcp:/lustre /lustre”. Both fail.
Since we almost run out of all space, I’ve put some important data onto
lustre. If this can’t be recovered, it will be a disaster to me… Hope
somebody can help me. Thanks a lot.

Luster client for Ubuntu 12.04
by Robert Stites
I need a Luster client for Ubuntu 12.04. My Lustre file system is running version 2.4 on Centos 6.4. Can someone give me a pointer to achieving this? I have compiled from git://git.whamcloud.com/fs/lustre-release.git and it crashes making the lustre-client using the command 'make debs'. Running 'make' compiles fine. Thanks.
