a. Run the
stopbackup -d
file_system_name command and the
stoprestore -d
file_system_name command to stop any backup or restore operation.
b.
Validate that no error occurred while stopping any Tivoli Storage Manager
service.
c. Run the
chkfs
file_system_name
-v | tee /ftdc/chkfs_fs_name.log2
command to recapture the output to a file.
d. Run the
startrestore
command and the
startbackup
command to enable
Tivoli Storage Manager.
If you receive an error message (the number of mounted or used nodes does
not matter) at step 5 of the command internal execution steps like the
following,
(5/9) Performing mmfsck call for the file system check stderr:
Cannot check. "gpfs0" is mounted on 1 node(s) and in use on 1 node(s).
mmfsck: Command failed.
Examine previous error messages to determine cause.
perform the following steps:
a. Monitor the
lsmount -r
command until the mount status changes to "not
mounted".
b. Run the
chkfs
file_system_name command again.
Review the new output file for errors and save it for IBM support to investigate
any problems. It is expected that the file contains
Lost blocks were found
messages. It is normal to have some missing file system blocks. If the only
errors that are reported are missing blocks, no further repair is needed.
However, if the
chkfs
command reports more severe errors, contact IBM
support to assist with repairing the file system.
Resolving an ANS1267E error
An ANS1267E error might indicate an incorrect setting in the Tivoli
®
Storage
Manager server configuration.
An ANS1267E error can result from the Tivoli Storage Manager server not being
set up to handle hierarchical storage management (HSM) migrated files. A return
of ANS1267E means that the management class is not accepting files from HSM.
The fix for this is to set “spacemgtech” to “auto”.
