Issue
- An ext3 filesystem mounted on a virtual disk LUN went read-only after a storage controller timeout and failover :
122 [RAIDarray.mpp]APOST0016-D1:0:0:4 Controller IO time expired. Delta 369 secs
497 [RAIDarray.mpp]APOST0016-D1:0:0:4 Failed controller to 1. retry. vcmnd SN 221098785 pdev H1:C0:T1:L4 0x00/0x00/0x00 0x00080000 mpp_status:14
10 [RAIDarray.mpp]APOST0016-D1:1 Failover command issued
801 [RAIDarray.mpp]Failover succeeded to APOST0016-D1:1
A short time later the journal was aborted and the filesystem went read-only :
