Error Message

'fsck -n' will show inconsistencies with EAU maps. For example

pass4 - checking resource maps
fileset 999 au 40 imap incorrect - fix (ynq)n
fileset 999 au 40 iemap incorrect - fix (ynq)n
fileset 999 au 80 imap incorrect - fix (ynq)n
fileset 999 au 103 imap incorrect - fix (ynq)n
au 45 emap incorrect - fix? (ynq)n au 45 summary incorrect - fix? (ynq)n
au 53 emap incorrect - fix? (ynq)n au 53 summary incorrect - fix? (ynq)n

The different flushing of different maps causes the on-disk filesystem to become inconsistent, if the log replay is interrupted.

The fsck log replay is updated to synchronously write secondary map and EAU summary to the disk.

During a filesystem mount operation, after the Intent log replay, a file system metadata corruption occurred. As part of the log replay during mount, fsck replays the transactions, rebuilds the secondary maps, and updates the Extent Allocation Unit (EAU) and the superblock summaries. Fsck flushes the EAU secondary map and the EAU summaries to the disk in a delayed manner, but the EAU state is flushed to the disk synchronously. As a result, if the log replay fails once before succeeding during the filesystem mount, the state of the metadata on the disk may become inconsistent. The above issue is applicable to All OS platforms (Linux, Solaris and AIX) from VXFS version 7.2 and above.
