I was trying to extend my LVM partition to another disk, but being late and my head not screwed on straight, things went terribly wrong. I was using diskdrake (from Mandrake) and what I did was create a LVM partition /dev/hdb6 and added it to my "quantum" VG which contained a single partition of /dev/hda6. I was simply doing this as a test (my first time using LVM), so as soon as it worked, I removed /dev/hdb6 from the "quantum" VG. I then proceeded to create a larger partition /dev/hdc that I wanted to add to "quantum" for good. I added it to the "quantum" VG and attemped to resize the "quantum" VG to the full size of both /dev/hda6 (17gb) and /dev/hdc (12gb). Everything "seemed" to go fine, so I exited from diskdrake and rebooted. During the reboot, it said it couldn't mount /dev/quantum/1 as it was not a proper block device. So I ran the following programs to try and collect as much data as possible: [root@ipso root]# pvscan -v pvscan -- reading all physical volumes (this may take a while...) pvscan -- walking through all physical volumes found pvscan -- inactive PV "/dev/hda6" is associated to an unknown VG (run vgscan) pvscan -- inactive PV "/dev/hdb6" is associated to an unknown VG (run vgscan) pvscan -- total: 2 [19.01 GB] / in use: 2 [19.01 GB] / in no VG: 0 [0] [root@ipso root]# vgscan -v vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d" vgscan -- reading all physical volumes (this may take a while...) vgscan -- no volume groups found vgcfgrestore -n quantum -l -f /etc/lvmconf/quantum.conf.1.old --- Volume group --- VG Name quantum VG Access read/write VG Status NOT available/resizable VG # 0 MAX LV 256 Cur LV 1 Open LV 0 MAX LV Size 255.99 GB Max PV 256 Cur PV 2 Act PV 2 VG Size 19 GB PE Size 4 MB Total PE 4865 Alloc PE / Size 4328 / 16.91 GB Free PE / Size 537 / 2.1 GB VG UUID 54LQnu-1gQl-mNuO-KR7U-yypa-woKi-iu7PRF [root@ipso lvmconf]# vgcfgrestore -n quantum -l -f /etc/lvmconf/quantum.conf --- Volume group --- VG Name quantum VG Access read/write VG Status NOT available/resizable VG # 0 MAX LV 256 Cur LV 1 Open LV 0 MAX LV Size 255.99 GB Max PV 256 Cur PV 3 Act PV 3 VG Size 30.88 GB PE Size 4 MB Total PE 7904 Alloc PE / Size 4328 / 16.91 GB Free PE / Size 3576 / 13.97 GB VG UUID 54LQnu-1gQl-mNuO-KR7U-yypa-woKi-iu7PRF [root@ipso lvmconf]# pvdata -a /dev/hda6 --- Physical volume --- PV Name /dev/hda6 VG Name quantum PV Size 16.91 GB / NOT usable 3.12 MB [LVM: 137 KB] PV# 1 PV Status NOT available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 4328 Free PE 0 Allocated PE 4328 PV UUID e42Ge3-mpoP-PNat-1xLg-TMjr-4hRU-Q2agG9 --- Volume group --- VG Name VG Access read/write VG Status NOT available/resizable VG # 0 MAX LV 256 Cur LV 1 Open LV 0 MAX LV Size 255.99 GB Max PV 256 Cur PV 2 Act PV 2 VG Size 19 GB PE Size 4 MB Total PE 4865 Alloc PE / Size 4328 / 16.91 GB Free PE / Size 537 / 2.1 GB VG UUID 54LQnu-1gQl-mNuO-KR7U-yypa-woKi-iu7PRF --- List of logical volumes --- pvdata -- logical volume "/dev/quantum/1" at offset 0 pvdata -- logical volume struct at offset 1 is empty pvdata -- logical volume struct at offset 2 is empty pvdata -- logical volume struct at offset 3 is empty pvdata -- logical volume struct at offset 4 is empty pvdata -- logical volume struct at offset 5 is empty pvdata -- logical volume struct at offset 6 is empty pvdata -- logical volume struct at offset 7 is empty pvdata -- logical volume struct at offset 8 is empty pvdata -- logical volume struct at offset 9 is empty pvdata -- logical volume struct at offset 10 is empty ... pvdata -- logical volume struct at offset 254 is empty pvdata -- logical volume struct at offset 255 is empty --- List of physical extents --- PE: 00000 LV: 001 LE: 00000 PE: 00001 LV: 001 LE: 00001 PE: 00002 LV: 001 LE: 00002 ...

I don't really care about /dev/hdb6 either, I would just like the data off of /dev/hda6. Partition table for: /dev/hda6 Device Boot Start End Blocks Id System /dev/hda1 * 1 507 255496+ 82 Linux swap /dev/hda2 508 39813 19810224 5 Extended /dev/hda5 508 4633 2079472+ 83 Linux /dev/hda6 4634 39813 17730688+ 8e Linux LVM Any ideas how I can get /dev/hda6 mountable again? Thanks. IpSo -------------------------------------------------------------------- Never worry about viruses in your Email again. Get your FREE! virus scanned Email accounts at http://snappymail.ca
