Is this one of the filesystems related to LU-11548? One of the problems seen in that case was multiple hard links to the same OST object. If that is the case here, it is possible that the "real" object was removed, but a hard linked name was left behind and the space was not freed.

Another possibility is that the object was migrated to a new MDT and the parent FID on the object was not updated. You might be able to search for large files in the directory (possibly belonging to UID 12137 and/or GID 21205) to see if that is the case?

lfs find /nobackupp8 -size +3T -print0 | xargs -0 ls -l

I assume there were not any other events around this time (eg. MDS or OSS crash)? That shouldn't cause an unlinked file to leave orphan objects behind, but knowing the circumstances around this file may help.

The orphan object(s) can be linked to /nobackupp8/.lustre/lost+found/ and/or unlinked by running lctl lfsck_start -A -t layout on the MDS (assuming this is not having other issues at the current time). Alternately, instead of running LFSCK, if the lfs find does not turn up any candidate files, you could mount the OST as type ldiskfs and delete the objects manually.

Comment by Mahmoud Hanafi [ 07/Nov/18 ]

This filesystem was not related to LU-11548. The only that may have happened here is the file was delete while it was still being written to from a different client. And then that write thread was killed.

Is it safe to mount the ost as ldiskfs and delete the object while the OST is mounted as lustre?

Comment by Andreas Dilger [ 07/Nov/18 ]

Officially, no. In theory, yes it is possible to do that (I sometimes do concurrent ldiskfs mounts on my home filesystem for debugging purposes), but it is not something we have officially tested. If you have a quiet time and could "expect" a crash, but are happy if it works without problems or interference with jobs, then I'd say it should probably be OK to do that. Otherwise, I'd suggest to wait until there is a scheduled outage window and try it then. At worst it would crash, but that is not much worse than just unmounting the OST (causing IO to block), remount as ldiskfs and remove the object, then remount the OST and go through recovery.

Comment by Mahmoud Hanafi [ 08/Nov/18 ]

I was able to delete the object after umounting OST and remount via ldiskfs.

Please close this issue.

Good news - thanks!

Comment by Andreas Dilger [ 09/Nov/18 ]

Reopening this issue because we don't know what the root cause is. We should be able to handle cleanup of open-unlinked files properly, and/or files that are unlinked from the MDT but held open when the MDS crashed.

I did a small test and saw that lfs fid2path does not report anything for an open-unlinked file:

client$ lfs path2fid /myth/tmp/1M
[0x200003ab4:0x435:0x0]
client$ sleep 10000 < /myth/tmp/1M &
[1] 13806
client$ sudo lfs fid2path /myth [0x200003ab4:0x435:0x0]
/myth/tmp/1M
mds# lctl get_param mdt.*.exports.*.open_files
mdt.myth-MDT0000.exports.192.168.20.159@tcp.open_files=[0x200003ab4:0x435:0x0]
client$ rm /myth/tmp/1M
mds# lctl get_param mdt.*.exports.*.open_files
mdt.myth-MDT0000.exports.192.168.20.159@tcp.open_files=[0x200003ab4:0x435:0x0]
client$ sudo lfs fid2path /myth [0x200003ab4:0x435:0x0]
lfs fid2path: cannot find '[0x200003ab4:0x435:0x0]': No such file or directory
client$ lsof /myth
COMMAND   PID   USER   FD   TYPE    DEVICE SIZE/OFF               NODE NAME
sleep   13806 mythtv    0r   REG 35,632494  1048576 144115440203858997 /myth/tmp/1M (deleted)

If this happens again in the future, it would be useful to check the mdt.*.exports.*.open_files list to see if the FID is listed there, which also lists the client NID that is holding it open, and you could use lsof on the client to find and kill the offending process (note that lsof will only report file handles open on the local node).

It would be useful if lfs fid2path listed these open-unlinked files directly, including the client NID and appends (deleted) as lsof does.
