Hi and welcome to the forums.

Usually lvol3 in the vg00 is the / (root) file system. This can be extended like other volumes. Volume should be continuous.


Please provide more info with you questions (like vgdisplay vg00 in this case).


regards,
ivan

Hi,

You will not be able to extend lvol3 (most cases it should be root filesystem) like any other filesystems. Since the PE's should be contigious. There are ways to extend if you have space and additional disks.

But the preferred and recommanded way to extend the root filesystem is taking ignite backup and restore. But again you should have free space on VG00 to achieve.

you can increase "lvol3" using ignite restoration.

Hi,

Lvol3 in vg00 is root (/), Please provide o/p of # vgdisplay -v vg00. There are ways to extend the root lvol, but none them is a recommended way. Try to free up root file system by deleting/ move unwanted files. If you really want to extend the root volume, please take ignite of your server and then restore the same. While restoring the ignite image you can specify the volume size as you wish.

Hi,

Did you check weather cron demon is running or not
ps -aef | grep -i cron
root 2894 1 0 Sep 28 ? 0:02 /usr/sbin/cron

If not then start it

Give full absolute path for each command which is using in crontab file.
