027 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.

028 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.
