WARNING: msgcnt x: mesg 027: V-2-27: vx_snap_bpcopy - mount_point
snapshot file system write error
■ Description
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.

WARNING: msgcnt x: mesg 028: V-2-28: vx_snap_alloc - mount_point
snapshot file system out of space
■ Description
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 too little disk space, or the
primary file system had an unexpected burst of activity. The
snapshot file system is disabled.
■ Action
Make sure the snapshot file system was given the correct amount
of space. If it was, determine the activity level on the primary file
system. If the primary file system was unusually busy, rerun the
backup. If the primary file system is no busier than normal, move
the backup to a time when the primary file system is relatively idle
or increase the amount of disk space allocated to the snapshot file
system.
Rerun any backups that failed when the error occurred.
