XFS filesystem error on openstack
Hi All,
We are having DELL Proliant 7xx machine. Where we have created a 4TB partition and re-directed all the ephemeral disks on it. Swift also lands over the same partition.
Things were running fine untill one day XFS crashed with some error as below :
Oct 29 15:32:02 host02 kernel: attempt to access beyond end of device
Oct 29 15:32:02 host02 kernel: sdb3: rw=32, want=6000000002, limit=5999218688

Oct 29 15:32:02 host02 object-replicator: Error syncing partition: [Errno 5] Input/output error: '/srv/node/sdb3/objects/496/tmpEGTvyp.tmp'
Has anyone else came across XFS filesystem error like this ? Any suggestions for Swift and ephemeral disks ?
