Re: [linux-lvm] PV-Move fails, now at 127 Pe's...


Found the 1.0.4.-pre1.tar.bz2, compiled, installed
(Hey, the fix to the 'cast' problem was already in there, although an old
version of the file was also!)
Was: Unable to clear last PE
>Well, you hit the cast problem I reported a fix for on linux-lvm shortly

- it *IS* possible to do the vgscan
- it *IS* possible to turn the volume active again
- it *IS* possible to do PV move again, and it does NOT fail on PE 127
- ALL data was still there !
- Everything is up and running !
- I am very very very happy !!!

Thanks a LOT, keep up the amazing work !!

Very kind regards,

So now the volume is inactive, I can't change it, although it notices
there is an inactive volume on the disks...

hdb1 and hdc1 both have 127 blocks on there now, and hdg1 has 2*127 block
removed. I can't access the data anymore now... Any suggestions on how to
get the volume back online, so the data can be accessed ???

vgscan -- only found 20391 of 20518 LEs for LV /dev/volume/data (0)
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't
get data of volume group "volume" from physical volume(s)

Yes, that's my guess.

Well, the way to go is:

- pvmove /dev/hdf2 # move your data back to /dev/hdf1
- vgreduce test12 /dev/hdf2
- update to LVM 1.0.3 (or wait for 1.0.4 which will be released soon)
- pvcreate /dev/hdf2
- vgextend test12 /dev/hdf2
- pvmove /dev/hdf1
