FW: error destroying object rc 115
by Shaw, Scott
From: Scott Shaw [mailto:sshaw@sgi.com]
Sent: Friday, March 03, 2017 12:00 AM

Subject: error destroying object rc 115
Hi,
I sent this email to the lustre-discussion mailing list but was rejected. So I apologize if this is a duplicate posting.
We are running into an issue with one OST logging errors destroying objects and I am not familiar with the process of addressing this issue. For this OST I have migrated and redistributed the objects to other OSTs so we don't lose any user data. Below is the messages file output from the OSS server presenting the OST002d target and the errors.
/var/log/messages from the OSS server:

{these errors keep cycling in the messages file}
>From the MDS server I initiated an LFSCK with a "-o" option so the MDT database would sync with the OST objects but oi_scrub shows no errors and the the OST oi_script cycles from completed to scanning.
I read the available documentation but I am not clear how to determine the object oi_scrub is showing an issue. Can someone help and provide a steps to fix this issue?

If I create a large 50GB sequential file I can see the used capacity increase but if I remove the file the used capacity does not decrease by 50GB.
On the MDS server oi_scrub shows no errors.
