lvsplit

[H_16]

I have just carried out a lvsplit -s 2212 /dev/vg01/lvol_u06_0512

However, it has named the split copy as lvol_u06_05122212. Is there anyway of renaming this lvol within LVM ??

Hi,

From the man page for lvsplit:

"If the -s option is specified, the new logical volume name has the
form lv_pathsuffix. If -s is not specified, suffix defaults to b, as
in lv_pathb."

So, the name lvol_u06_05122212 is exactly what should have resulted.

I don't believe you can rename the lvol without going through some sort of vgexport/vgimport scenario and massaging the lvol names during the import.

Hi,

Yes you can simply do it by renaming BOTH /dev/vg01/lvol_u06_05122212 and /dev/vg01/rlvol_u06_05122212. Just use 'mv' but check first that they are not mounted. This can be done even with vg activated. Renaming a vg is harder because it needs the export/import.

I suppose you could join it together again "lvmerge" and then try again witha different suffix, or non at all.

You can actually rename the actual files in /dev/vg01 now on the split volume. It will work just fine.

Just make sure you get the character device and the blcok device and its corresponding character device.

I usually use the mv command.

Hi,

You can merge the lvol again
#lvmerge /dev/vg01/lvol_u06_0512 /dev/vg01/2212
(/usr/sbin/lvmerge [-A autobackup] dest_lv_path src_lv_path )
and redo the lvsplit with the name you want specified.

I believe that with mv command, could to be renamed!

Logical volume names are only for user conveinence and ease of use. LVM deals with lvols by their device minor numbers only, it could care less what the name is. The LVM commands display the lvol name by looking at the name of the corresponding device file in /dev/vgxx/lvol....
