[Gluster-users] Unable to delete file - no such file or directory
Hello,
I have faced strange problem on one of the Gluster client/server nodes. File
exist but cannot be deleted from the fuse mount point on one client node, but
can be deleted from another
Attemt to delete:
root at SERVER:~# rm /var/lib/nova/instances/instance-0098a323/disk
rm: cannot remove `/var/lib/nova/instances/instance-0098a323/disk': No such
file or directory
Although files listed as existing in the volume:
root@ SERVER:~# ls -al /var/lib/nova/instances/instance-0098a323
total 6143442
drwxrwxr-x 2 nova nova 143 Jun 11 11:54 .

Subvolume information:
volume glustervmstore-replicate-3
type cluster/replicate
subvolumes glustervmstore-client-6 glustervmstore-client-7
end-volume
volume glustervmstore-replicate-21
type cluster/replicate
subvolumes glustervmstore-client-42 glustervmstore-client-43
end-volume
It is also available on the replica bricks. However I WAS ABLE to delete the
file from another node, which also mounts the same volume under:
/var/lib/nova/instances
Log file excerpt (I presume that?s /var/log/gluster/var-lib-nova-instances.log).
What is strange that glustervmstore-client-6 and glustervmstore-client-6 does
not represent actual brick servers where file is stored:

The same happened for /instance-0098a327/disk file although there are no
similar line

g conservative merge
I was able to delete the file from another node.
There are no mention of the folder in the GlusterFS logs on the actual brick
servers.
Thank you
