[Gluster-users] how to check/fix underlaying partition error?

[Sander Zijlstra]

Hi Pavel,

you can simply stop the glusterd service and run the fsck, it's similar to rebooting a server which is part of a replicated volume. If all is ok before you can simply take down one of the two and once it comes back online it will be heal each file which hasn't been copied allready.

Do take care of any client which has the volume mounted using the server you take down; that will loose connection also.

Met vriendelijke groet / kind regards,

Hi guys,

I have replicated glusterfs (v3.4.2) on two server and I found logs 
filled by IO error on one server only. But in /var/log/messages is no hw 
error, only XFS error, so I gues the filesystem could be corrupted

My question is, how to stop or pause this brick and run fsck ?
 From the replicate feature I'm expecting no need to stop the gluster 
volume (there are some xen VM running)

what is the right way to do it? with the later re-adding and fast 
rebuild/sync in mind..

thank for tips

Pavel
