Backup, restore, and recovery problems

Description

At the end of an HSM file system recovery, some files are reported as being 'reserved' in the

 

output of the fserecover command.

Explanation

The word reserved means that file IDs were assigned to new files on the HSM file system, but

 

these files had been either deleted or changed before they could have been migrated using

 

these particular file IDs. Such file IDs were only recorded in the File System Catalog. These files

 

have been migrated using other, newly generated, file IDs. The “reserved” entries therefore, do

 

not indicate data loss.

Workaround

None

Description

After recovery of an HSM file system, files that were previously deleted from the HSM file

 

system are recreated, but online files that still existed are truncated.

 

(Windows FSE client specific)

Explanation

n/a

Workaround

Proceed as follows:

 

1.

Delete obsolete files from the HSM file system once again.

 

2.

If you want truncated files to be immediately available, use the fsefile command to

 

 

recall them manually.

 

 

In the opposite case truncated files will be automatically recalled at first access.
