HP-UX

Question
I am not a hp admin but aix admin.
I am wondering if to increase the fs /var we really have to umount the fs so means stop the system ... just to do an extendlv ?
It is what I saw on man page of extendlv and that surprise me. On aix we can dynamically increase a fs and with version 5.3 can dynamically also reduce a fs. I would like to assume that on HP-UX we can also dynamically increase a fs... I hope so that I have to add some space to /var as it is a little full and the only files that I found big is belong to legato networker and don't know how to free space and nobodies no !

/var/nsr/index/hostname/db # ls -ltr
total 1033440
-rw------- 1 root root 472162304 Feb 16 10:51 sr.0
-rw------- 1 root root 28491776 Feb 16 10:56 sr_i0.0
-rw------- 1 root root 32768 Feb 16 11:11 sr_i1
-rw------- 1 root root 28336128 Feb 16 11:11 sr_i1.0
-rw------- 1 root root 8192 Feb 16 12:33 VolHdr
-rw------- 1 root root 32768 Feb 16 12:33 sr
-rw------- 1 root root 32768 Feb 16 12:33 sr_i0

Please if you can give me some help it will be cool.

Cheers.

The /var fs should be in the VG vg00. Check if vg00 has any free extents using vgdisplay. If it does, then you can use lvextend to extend the logical volume for /var. Finally, when you do get some downtime, take the system down to single user mode, unmount the filesystem and run extendfs to extend the filesystem to the new size of the logical volume.

Alternatively, if you do have the license for fsadm, you can use that utility to extend the filesystem online, without any downtime.

Try this:

1. reboot.
2. Single user in boot
3. umount fs
4. increase /var
