• Explanation
Snapshot file system error.
When the primary file system is written, copies of the original data
must be written to the snapshot file system. If a read error occurs on
a primary file system during the copy, any snapshot file system that
doesn’t already have a copy of the data is out of date and must be
disabled.
• Action
An error message for the primary file system prints. Resolve the error
on the primary file system and rerun any backups or other
applications that were using the snapshot that failed when the error
occurred.
Message 027 WARNING: msgcnt x : vxfs: mesg 027: vx_snap_bpcopy -
mount_poin t snapshot file system write error
• Explanation
A write to the snapshot file system failed.
As the primary file system is updated, copies of the original data are
read from the primary file system and written to the snapshot file
system. If one of these writes fails, the snapshot file system is
disabled.
• Action
Check the console log for I/O errors. If the disk has failed, replace it.
Resolve the error on the disk and rerun any backups or other
applications that were using the snapshot that failed when the error
occurred.
Message 028 WARNING: msgcnt x : vxfs: mesg 028: vx_snap_alloc -
mount_point snapshot file system out of space
• Explanation
The snapshot file system ran out of space to store changes.
During a snapshot backup, as the primary file system is modified, the
original data is copied to the snapshot file system. This error can
occur if the snapshot file system is left mounted by mistake, if the
snapshot file system was given toolittle disk space, or the primary file
system had an unexpected burst of activity. The snapshot file system
is disabled.
