storageset command done)
• Concatsets cannot be partitioned, and a partitioned storageset cannot be used in
a concatset
• Once created, the only way to delete the concatset is to delete the unit that is
on top of the concatset, then delete the concatset. An entity can be inserted
into a concateset, but not removed.
• When going from a build that supports concatsets to a build that does not
support a concatset, a shutdown must be done.
• A CLONE cannot be done on a concatset.
The following steps should be used to expand a concatset.
Note: the following steps assume the user has a good understanding of the Veritas
Filesystem software product. Refer to the Veritas Filesystem documentation for more
information.
1.
Assume the user has an existing raidset (R1) that has a Veritas filesystem (vxfs) on
it. The raidset, R1, should be a member of a concatset (assume C1).
Note: This procedure only works with Veritas Filesystem version 3.3. Do not
attempt it without the Veritas Filesystem software, or data loss will result!
2. Perform a complete system backup.
3.
To check the size of the filesystem, use the following command:
df –F vxfs
4. Stop I/O, and unmount the filesystem, with the following command:
umount /mnt/test (your directory name will be
different)
5. Now that the unit is unmounted, you can use then following CLI command to
expand the storageset:
set C1 replace=R2
This will add raidset R2 into the concatset consisting of R1. The size of C1 is now
R1 + R2, without affecting the existing data on C1.
6.
Now you must run the format command to update the unit’s VTOC (label).
Perform the following steps:
Run format
Select the unit that you just expanded.
Select type to update the unit’s logical geometry.
Select option 0 to auto configure the unit’s logical geometry.
Select label to write the new label (with updated logical geometry) to the unit.
Exit the format program.
7.
Re-mount the filesystem with the following command:
mount –F vxfs /dev/dsk/c4t65d0s0 /mnt/test (your
devicename and directory will be different).
8. Now use the Veritas fsadm command to expand the size of the filesystem.
/usr/lib/fs/vxfs/fsadm –F vxfs –b 141083136 /mnt
Note: your number of blocks will vary. Use the number of blocks that was detected
by the format command in step number 6 (less diagnostic tracks).
