I am trying to move some large directories on the same lustre filesystem
however I can see that instead of quick name remapping mv does copy
operation. Is there a way to avoid this?
As a test I created new directory with hundreds of large files and moved it
and mv works as expected. I do not understand what is different about the
other directories that they can not be simply moved.

I would like to report about a strange issue I have seen with HP's HPC
SFS G3.2-3 running an early version of Lustre 1.8, (I believe it was
1.8.3) on Centos 5.3.
lustre_config could create the ldiskfs on the ext2 level, but then
exited with the following message on all OSSes:
mkfs.lustre FATAL: failed to write local files
I could mount the OSTs as ldiskfs, but there was no CONFIGS directory.
When I tried to create one manually, the node crashed immediately, but I
have found the following entry in /var/log/messages:
Mar 18 10:51:15 sfs3 kernel: LDISKFS-fs error (device dm-1):
ldiskfs_ext_find_extent: :463: bad header in inode #229302273: invalid
magic - magic 0, entries 0, max 0(0), depth 0(0)
I upgraded e2fsprogs to the latest version, but again, lustre_conrfig
failed. I ran an e2fsck on the osts, which seemed to fix the problem
according to its output, and a second run of e2fsck confirmed that
everything was ok. However, when I mounted the OST as ldiskfs again and
tried to create the CONFIGS directory the node crashed again.
The solution to this problem was: Installing lustre 1.8.9 from
whamcloud. After that I hit another minor issue
(https://jira.hpdd.intel.com/browse/LU-4789), but after fixing that one
lustre_config completed successfully. Either this was a bug which was
fixed between 1.8.3 and 1.8.9, or there was an issue with an expired
license which caused the lustre shipped with the SFS to behave
strangely. I believe the second explanation is the better one, because
the exact same thing has worked some years ago and has stopped working
after the support contract has ended (installed software has remained
unchanged since then).
Can someone provide more info on "/etc/init.d/lustre" that is included in the 2.4.3 client? Looks like it's doing bunch of stuff related to RAID and zpools. I then spotted LU-4707:
Any way of rebuilding the client without this init script?
So, Peter, are you saying that Lustre 1.8.9 clients will not work or be
supported with Lustre 2.5.x servers?

I must implement a new lustre file system and optimize it to get a high level of performance. I wonder: can I get more performance, If I split the MDS and the MGS in two different machines?
