Remove Ghost Volume Group

[normntwrk]

We have an F80 that to make a long story short one of the power supplies failed and that seemed to have nuked the Raid 5 arrays. We were able to get one of the Raid Arrays back intact but we can't get the other Array back so it will stay configured after the machine reboots (it comes up either dead or the drives come up as failed or it just refuses to rebuild after I revive the drives.)

Anyway for now we are going to run with one Raid array as it is big enough for what we need for now. My issue is that I have a "Ghost" array sitting out there and I can't remove it. The documentation says that to do a reducevg it needs to be varied on which of course I can't do as it doesn't exist.

Any Ideas?

Thanks,

still trying to see your ghost VG:

Please post "lsvg" output.

"Long live king Moshiach !"

http://www.7for70.com/

 

[normntwrk]

Here is lsvg, I see I actually have 2 "Ghosts",... raidvg1 and raidvg2 are not there

# lsvg
rootvg
raidvg1
raidvg3
raidvg2


thanks

 

[MoshiachNow]

Try:

varyoffvg raidvg2
exportvg raidvg2

"Long live king Moshiach !"

http://www.7for70.com/

 

[normntwrk]

#varyoffvg raidvg2
0516-010 lqueryvg: Volume group must be varied on; use varyonvg command.
0516-010 lqueryvg: Volume group must be varied on; use varyonvg command.
0516-010 lvaryoffvg: Volume group must be varied on; use varyonvg command.
0516-942 varyoffvg: Unable to vary off volume group raidvg2.

[MoshiachNow]

As chapter11 said,try:

exportvg raidvg2

"Long live king Moshiach !"

http://www.7for70.com/

 

[normntwrk]

Did that, also tried this

# varyonvg raidvg1
PV Status: 0000f04fb413f7fd PVNOTFND
0516-013 varyonvg: The volume group cannot be varied on because
there are no good copies of the descriptor area.
# reducevg raidvg1 0000f04fb413f7fd
0516-010 lqueryvg: Volume group must be varied on; use varyonvg command.
0516-882 reducevg: Unable to reduce volume group.

What does 'odmget CuDv | grep -p raidvg2' say?

Try 'odmdelete -o CuDv -q "name = raidvg2"'
and 'odmdelete -o CuDv -q "parent = raidvg2"'

P.S. Take a backup first.

Cheers

 

[normntwrk]

# odmget CuDv | grep -p raidvg2
CuDv:
name = "raidvg2"
status = 0
chgstatus = 1
ddins = ""
location = ""
parent = ""
connwhere = ""
PdDvLn = "logical_volume/vgsubclass/vgtype"

 

[unixfreak]

If you delete it does your problem go away?

Cheers

 

[normntwrk]

I don't really have any experience with the ODM and I don't think anyone else here does either. We are just getting this machine restored from Tape to the good array so I think I will live with the Ghosts for the time being and tackle them later.

I think you've got me going in the right direction

Thanks a million

I see you posted a few logs from running other vg-related commands, but nothing that indicates you tried exportvg.

 

[normntwrk]

I tried the exportvg and it didn't return anything.....no errors or any information. Did it for raidvg1 and raidvg2

 

[Chapter11]

exportvg generally won't return anything. do an lsvg now and see if they are gone.

 

[normntwrk]

still there

# lsvg
rootvg
raidvg1
raidvg3
raidvg2

 

[Chapter11]

hmmm. At this point it looks like odm hacking time. Sorry 'bout that.
