Hi,
In short: adding a new HDD to an LVM group didn't work somehow and now it won't mount the disk(s), and I get this at boot:
The disk drive for /movies is not ready yet or not present.
I have a 12.04 installation with 2 hard drives (no RAID) and an LVM setup with a few volumes... I tried to add a new HDD to the machine and add it to the volume group, following the instructions at: http://www.howtogeek.com/howto/40702...ent-in-ubuntu/
My volume group is called vg,
the logical volume in question is called vgmovies, mounted at /movies
Retracing my steps (should be accurate):
I used fdisk to make a new primary LVM partition the full size of the disk... /dev/sdc1
then pvcreate for the disk
then vgextend vg /dev/sdc1
then lvresize -l +100%FREE /dev/vg/vgmovies
then resize2fs /dev/vg/vgmovies
(last command took a long time)
It all seemed to go well and df -h showed a nice big (3.6TB) volume.
I restarted and had problems. To begin with, I only had /dev/sdc, not sdc1 (not sure why).
At one point I added sdc as a PV (mistake), but later recreated the partition and sdc1 has stuck now (and sdc is not in the LVM).
I've tried 100 different things since and can't fix it. (So some of the current problems are different than the initial issues probably.) Please help
The current state seems to be that everything is there - the PV is present - but LVM thinks it's missing.
http://osdir.com/ml/linux-lvm/2013-10/msg00041.html (and other places) suggests that vgextend --restoremissing should do it, but I get "vgextend: unrecognised option '--restoremissing'" !!
I have not seen this error online, so don't know what to do with it.
Here are some outputs. Let me know any other commands that would be helpful.
Here's the output of dmesg: http://paste.ubuntu.com/7508473/ (I have a failing drive, /dev/sda, which is why I was adding a new one.)Code:lindsay@htpc:~$ sudo lvm version LVM version: 2.02.66(2) (2010-05-20) Library version: 1.02.48 (2010-05-20) Driver version: 4.22.0 lindsay@htpc:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-vgroot 19G 6.2G 12G 35% / udev 1.8G 4.0K 1.8G 1% /dev tmpfs 741M 1008K 740M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1.9G 84K 1.9G 1% /run/shm /dev/sdb1 473M 53M 398M 12% /boot /dev/mapper/vg-vghome 9.3G 3.0G 5.9G 34% /home /dev/sda1 68G 11G 54G 17% /slashDisk1 /dev/sda5 851G 473G 335G 59% /disk1 lindsay@htpc:~$ sudo fdisk -l Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e55dd Device Boot Start End Blocks Id System /dev/sda1 * 63 141837884 70918911 83 Linux /dev/sda3 141837885 1953520064 905841090 5 Extended /dev/sda5 141837948 1953520064 905841058+ 83 Linux Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x000d1e6b Device Boot Start End Blocks Id System /dev/sdb1 * 2048 976895 487424 83 Linux /dev/sdb2 976896 3907028991 1953026048 8e Linux LVM Disk /dev/sdc: 2000.4 GB, 2000398934016 bytes 81 heads, 63 sectors/track, 765633 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xbc04db52 Device Boot Start End Blocks Id System /dev/sdc1 2048 3907029167 1953513560 83 Linux Disk /dev/mapper/vg-vgroot: 20.0 GB, 19998441472 bytes 255 heads, 63 sectors/track, 2431 cylinders, total 39059456 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg-vgroot doesn't contain a valid partition table Disk /dev/mapper/vg-vghome: 9999 MB, 9999220736 bytes 255 heads, 63 sectors/track, 1215 cylinders, total 19529728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg-vghome doesn't contain a valid partition table Disk /dev/mapper/vg-vgswap: 4999 MB, 4999610368 bytes 255 heads, 63 sectors/track, 607 cylinders, total 9764864 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg-vgswap doesn't contain a valid partition table lindsay@htpc:~$ sudo pvdisplay -m --- Physical volume --- PV Name /dev/sdb2 VG Name vg PV Size 1.82 TiB / not usable 4.00 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 476812 Free PE 0 Allocated PE 476812 PV UUID XHeIXt-d3xr-Wo1f-rZF9-7rCm-nvey-AfJ0QU --- Physical Segments --- Physical extent 0 to 4767: Logical volume /dev/vg/vgroot Logical extents 0 to 4767 Physical extent 4768 to 7151: Logical volume /dev/vg/vghome Logical extents 0 to 2383 Physical extent 7152 to 8343: Logical volume /dev/vg/vgswap Logical extents 0 to 1191 Physical extent 8344 to 476811: Logical volume /dev/vg/vgmovies Logical extents 0 to 468467 --- Physical volume --- PV Name /dev/sdc1 VG Name vg PV Size 1.82 TiB / not usable 4.09 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 476931 Free PE 0 Allocated PE 476931 PV UUID AYUyq4-1YYp-kOK2-FYyB-qRjV-nZKx-vie8lT --- Physical Segments --- Physical extent 0 to 476930: Logical volume /dev/vg/vgmovies Logical extents 468468 to 945398 lindsay@htpc:~$ sudo vgdisplay --- Volume group --- VG Name vg System ID Format lvm2 Metadata Areas 2 Metadata Sequence No 19 VG Access read/write VG Status resizable MAX LV 0 Cur LV 4 Open LV 3 Max PV 0 Cur PV 2 Act PV 1 VG Size 3.64 TiB PE Size 4.00 MiB Total PE 953743 Alloc PE / Size 953743 / 3.64 TiB Free PE / Size 0 / 0 VG UUID KoLIJC-xIB9-uKKh-Q7Ba-nfQR-Hf8I-OqsXS5 lindsay@htpc:~$ sudo lvdisplay --- Logical volume --- LV Name /dev/vg/vgroot VG Name vg LV UUID iNv6Ss-DDbi-IFdG-dSmB-Ewee-Rxzc-AZvI8L LV Write Access read/write LV Status available # open 1 LV Size 18.62 GiB Current LE 4768 Segments 1 Allocation inherit Read ahead sectors auto -

I don't want to lose the data in vgmovies, but there is nothing on the new disk. I am quite happy to remove it from the VG and start again, but I can't.
I don't know what else to try. Thank you in advance for your suggestions!
