Problem

Block Level Incremental backup fails with status 6. The client's bpbkar log shows "Cannot mount checkpoint."

Error Message

The VERBOSE  /usr/openv/netbackup/logs/bpbkar log reveals the entire problem.  

First, it indicates the fsckpt_setcontext failed and reported message Errno = 48: Operation not supported.
Then it shows the mount checkpoint command followed by the error "Cannot mount checkpoint"

A snippet from the bpbkar log:

<4> bpbkar set_clone_context: INF - fsckpt_setcontext to NetBackup_full_Neptune_OSPK_1101144201 failed.
Filesystem = /app1/oracle/oradata21. Errno = 48: Operation not supported
<4> bpbkar set_clone_context: /usr/sbin/mount -F vxfs -ockpt=NetBackup_full_Neptune_OSPK_1101144201 dev/vx/dsk/spkproddatadg01/spkproddatadg01-oradata21:NetBackup_full_Neptune_OSPK_1101144201 /app1/oracle/oradata21/NetBackup_checkpoints/NetBackup_full_Neptune_OSPK_1101144201 >/dev/null 2>/dev/null
] <16> bpbkar set_clone_context: Cannot mount checkpoint NetBackup_full_Neptune_OSPK_1101144201 on /app1/oracle/oradata21/NetBackup_checkpoints/NetBackup_full_Neptune_OSPK_1101144201.
........
11:26:13.918 [15506] <16> bpbkar Exit: bpbkar FATAL exit status = 6: the backup failed to back up the requested files

 

Cause

A close look at the mount command reveals an attempt to mount the checkpoint on a filesystem that has not been mounted with the absolute path.

Additional information:
The mount -v command confirms the filesystems have been mounted without the absolute path.

mount -v

Solution

Solution:

Unmount and remount the filesystem using the absolute path name and correct options.
 
mount command is an operating system command - consult your system administrator if in doubt.
