Invalid partition specified, or partition table wasn't reread after running fdisk, due to a modified partition being busy and in use. You may need to reboot to re-read your partition table. I found this mailing list post [http://www.redhat.com/archives/linux-lvm/2006-April/msg00047.html] and thought that maybe one of my pvs was bad, so I tried to add a new pv (sda12) and migrate off of the most-recently-added one (sda11), but the 'pvmove' command gave a similar error and said to run 'pvmove --abort'. But that just hung. I tried to shut down in order to abort it, but that hung 'unmounting local filesystems'. When I forced a reboot, another of my volumes (named gen-website) seemed to have been lost. My first try sending this message included a level 7 log file as an attachment. I think the mailing list may have rejected the message because it was too big (262k), so I'm excluding it for now. Below are some more details on my setup. Forgive me if there's extraneous stuff here, but I want to try to provide as much detail as necessary; if there's any more info that would be useful, please let me know. # uname -a Linux localhost 2.6.14-gentoo-r5 #4 SMP PREEMPT Wed Sep 13 22:40:49 EDT 2006 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz GNU/Linux # lvm version LVM version: 2.02.06 (2006-05-12) Library version: 1.02.07 (2006-05-11) Driver version: 4.4.0 # fdisk -l /dev/sda Disk /dev/sda: 320.0 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 17 136521 83 Linux /dev/sda2 18 34 136552+ da Non-FS data /dev/sda3 35 66 257040 da Non-FS data /dev/sda4 67 38913 312038527+ 5 Extended /dev/sda5 67 1312 10008463+ 83 Linux /dev/sda6 1313 3803 20008926 8e Linux LVM /dev/sda7 3804 8784 40009851 8e Linux LVM /dev/sda8 8785 18745 80011701 8e Linux LVM /dev/sda9 18746 28706 80011701 8e Linux LVM /dev/sda10 28707 33687 40009851 8e Linux LVM /dev/sda11 33688 36178 20008926 8e Linux LVM /dev/sda12 36179 38668 20000893+ 8e Linux LVM /dev/sda13 38669 38913 1967931 83 Linux # pvs /dev/cdrom: read failed after 0 of 4096 at 0: Input/output error PV VG Fmt Attr PSize PFree /dev/sda10 maingroup lvm2 a- 38.15G 516.00M /dev/sda11 maingroup lvm2 a- 38.15G 23.15G /dev/sda12 maingroup lvm2 a- 19.07G 4.07G /dev/sda6 maingroup lvm2 a- 19.08G 0 /dev/sda7 maingroup lvm2 a- 38.15G 0 /dev/sda8 maingroup lvm2 a- 76.30G 0 /dev/sda9 maingroup lvm2 a- 76.30G 0 # vgs /dev/cdrom: read failed after 0 of 4096 at 0: Input/output error VG #PV #LV #SN Attr VSize VFree maingroup 7 12 0 wz--n- 305.21G 27.73G # lvs /dev/cdrom: read failed after 0 of 4096 at 0: Input/output error LV VG Attr LSize Origin Snap% Move Log Copy% c-p maingroup -wi-a- 4.00G capture maingroup -wi-ao 68.00G gen-website maingroup -wI-d- 15.00G home maingroup -wi-ao 110.00G music maingroup -wi-ao 30.00G opt maingroup -wi-ao 4.00G swap1 maingroup -wi-ao 1.00G swap2 maingroup -wi-ao 1.00G tmp maingroup -wi-ao 2.00G usr maingroup -wi-ao 20.00G var maingroup -wi-ao 7.49G # dmsetup table maingroup-tmp: 0 4194304 linear 8:8 154018176 maingroup-c--p: 0 8388608 linear 8:7 47980928 maingroup-capture: 0 23642112 linear 8:7 56369536 maingroup-capture: 23642112 40009728 linear 8:6 384 maingroup-capture: 63651840 78954496 linear 8:10 384 maingroup-usr: 0 19996672 linear 8:9 73400704 maingroup-usr: 19996672 974848 linear 8:8 150946176 maingroup-usr: 20971520 3891200 linear 8:8 48619904 maingroup-usr: 24862720 7708672 linear 8:8 384 maingroup-usr: 32571392 9371648 linear 8:8 52511104 maingroup-var: 0 10485760 linear 8:9 62914944 maingroup-var: 10485760 5218304 linear 8:8 145727872 maingroup-gen--website: maingroup-music: 0 1810432 linear 8:8 158212480 maingroup-music: 1810432 17317888 linear 8:9 142705024 maingroup-music: 19128320 43786240 linear 8:7 384 maingroup-swap2: 0 2097152 linear 8:7 45883776 maingroup-opt: 0 2097152 linear 8:8 151921024 maingroup-opt: 2097152 6291456 linear 8:8 42328448 maingroup-dvd: maingroup-swap1: 0 2097152 linear 8:7 43786624 maingroup-pvmove0: maingroup-home: 0 62914560 linear 8:9 384 maingroup-home: 62914560 29310976 linear 8:9 113394048 maingroup-home: 92225536 19996672 linear 8:9 93397376 maingroup-home: 112222208 34619392 linear 8:8 7709056 maingroup-home: 146841600 83845120 linear 8:8 61882752 ---------------------- Matt McHenry http://www.speakeasy.org/~jerith/ jerith@speakeasy.org be052@scn.org
