lvmconf file size is too big after ignite recovery

[Deepak.R]

Hi,

I have taken ignite backup in ignite server and restored in new hardware.

After recovery, when i create any new VG or import any existing VG, the size of the /etc/lvmcong/.conf is too big(almost each vg conf file size is 16MB). This making root file system full .

The sizes of .conf files in the server where from the ignite backup was taken comparitively very small.

regards,
Madhu

This should only be the case if the vgs are set up -max_lv 255 -peperpv 65535 -max_pv 255 while having a low pe size.

(At a customer site we had that config for some time, and also found to have certain 'issues' of / filling up)

You should look into the ignite client_config files, the vg parameters there would be highly interesting.

Emergency workaround:
extra LV for /etc/lvmconf (for some reason I'll never grasp, this really works fine ;)

Hi Deepak,

You can move the /etc/lvmconf/ *.conf.old files , to free up some space.

Cheers,

Hi,

It appears that some VG parameters are set to very high values as posted above. Could you post "vgdisplay -v /dev/vgXX" output for any such VG.

Key Parameters to be noticed.
1) PE_SIZE
2) MAX_PE_PER_PV
3) MAX_PV_PER_VG

HTH,
Devender

You could also have a corrupted ioconfig file. If this iGnite is building new server and you could pvcreate the disks, I would suggest:
1. Disconnect your hbas
2. Remove all ref in /dev/dsk & /dev/rdsk except vg00 and CDs
3. ioscan -fn
4. insf -e
5. Recreate your VGs
