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 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 ?
