Hi,
I have a disperse gluster volume with 6 servers. 262TB of
usable capacity. Gluster version is 3.7.19.
glusterfs1, glusterf2 and glusterfs3 nodes were initially used
for creating the volume. Nodes glusterf4, glusterfs5 and glusterfs6 were
later added to the volume.
Directory creation failed on a directory called
/ws/glus/Folder_07.11.2016_23.02/CV_MAGNETIC.
# file: ws/glus/Folder_07.11.2016_23.02/CV_MAGNETIC
glusterfs.gfid.string="e8e51015-616f-4f04-b9d2-92f46eb5cfc7"
gluster mount log contains lot of following errors:
[2017-03-09 15:32:36.773937] W [MSGID: 122056]
[ec-combine.c:875:ec_combine_check] 0-StoragePool-disperse-7:
Mismatching xdata in answers of 'LOOKUP' for
e8e51015-616f-4f04-b9d2-92f46eb5cfc7
The directory seems to be out of sync between nodes glusterfs1,
glusterfs2 and glusterfs3. Each has different version.
trusted.ec.version=0x00000000000839f00000000000083a4d
trusted.ec.version=0x0000000000082ea40000000000083a4b
trusted.ec.version=0x0000000000083a760000000000083a7b
Self-heal does not seem to be healing this directory.
This is very similar to what happened the other time. Once more than 1
brick is damaged, self-heal cannot do anything to heal it on a 2+1
configuration.
What error does return the mkdir request ?
Does the directory you are trying to create already exist on some brick ?
Can you show all the remaining extended attributes of the directory ?
It would also be useful to have the directory contents on each brick (an
'ls -l'). In this case, include the name of the directory you are trying
to create.
Can you explain a detailed sequence of operations done on that directory
since the last time you successfully created a new subdirectory ?
including any metadata change.
Xavi
Thanks and Regards,
Ram
