The following example restores a file system from the Storage Checkpoint CKPT3
. The filesets listed before the restoration show an unnamed root fileset and six Storage Checkpoints.
To restore a file system from a Storage Checkpoint
Run the fsckpt_restore command:
# fsckpt_restore -l /dev/vx/dsk/dg1/vol2 /dev/vx/dsk/dg1/vol2: UNNAMED: ctime = Thu 08 May 2004 06:28:26 PM PST mtime = Thu 08 May 2004 06:28:26 PM PST flags = largefiles, file system root CKPT6: ctime = Thu 08 May 2004 06:28:35 PM PST mtime = Thu 08 May 2004 06:28:35 PM PST flags = largefiles CKPT5: ctime = Thu 08 May 2004 06:28:34 PM PST mtime = Thu 08 May 2004 06:28:34 PM PST flags = largefiles, nomount CKPT4: ctime = Thu 08 May 2004 06:28:33 PM PST mtime = Thu 08 May 2004 06:28:33 PM PST flags = largefiles CKPT3: ctime = Thu 08 May 2004 06:28:36 PM PST mtime = Thu 08 May 2004 06:28:36 PM PST flags = largefiles CKPT2: ctime = Thu 08 May 2004 06:28:30 PM PST mtime = Thu 08 May 2004 06:28:30 PM PST flags = largefiles CKPT1: ctime = Thu 08 May 2004 06:28:29 PM PST mtime = Thu 08 May 2004 06:28:29 PM PST flags = nodata, largefiles
In this example, select the Storage Checkpoint CKPT3
as the new root fileset:
Select Storage Checkpoint for restore operation or <Control/D> (EOF) to exit or <Return> to list Storage Checkpoints: CKPT3 CKPT3: ctime = Thu 08 May 2004 06:28:31 PM PST mtime = Thu 08 May 2004 06:28:36 PM PST flags = largefiles UX:vxfs fsckpt_restore: WARNING: V-3-24640: Any file system changes or Storage Checkpoints made after Thu 08 May 2004 06:28:31 PM PST will be lost.

(Yes)
UX:vxfs fsckpt_restore: INFO: V-3-23760: File system

If the filesets are listed at this point, it shows that the former UNNAMED root fileset and CKPT6
, CKPT5
, and CKPT4
were removed, and that CKPT3
is now the primary fileset. CKPT3
is now the fileset that will be mounted by default.
Run the fsckpt_restore command:
# fsckpt_restore -l /dev/vx/dsk/dg1/vol2 /dev/vx/dsk/dg1/vol2: CKPT3: ctime = Thu 08 May 2004 06:28:31 PM PST mtime = Thu 08 May 2004 06:28:36 PM PST flags = largefiles, file system root CKPT2: ctime = Thu 08 May 2004 06:28:30 PM PST mtime = Thu 08 May 2004 06:28:30 PM PST flags = largefiles CKPT1: ctime = Thu 08 May 2004 06:28:29 PM PST mtime = Thu 08 May 2004 06:28:29 PM PST flags = nodata, largefiles Select Storage Checkpoint for restore operation or <Control/D> (EOF) to exit or <Return> to list Storage Checkpoints:
