Filesystem on VMware Red Hat Enterprise Linux 4, 5, 6, 7 & 8 guests went read-only
Issue
- File systems became read-only on virtual guests on VMware.
- The read-only filesystem was caused by temporary disconnections to SAN disks, VM crashed. how can we avoid it?
- Read-only filesystem is occurring fairly regularly.
- Root file system went to read only mode in RHEL 4 VM running on VMware and server got panic. Need to reboot the server to overcome the situation, how can we avoid this behavior?
-
Filesystem went to ready only mode, we had following SCSI I/O error events logged in syslog messages:
kernel: sd 0:0:0:0: timing out command, waited 1080s kernel: sd 0:0:0:0: Unhandled error code kernel: sd 0:0:0:0: SCSI error: return code = 0x06000008 kernel: Result: hostbyte=DID_OK driverbyte=DRIVER_TIMEOUT,SUGGEST_OK
