Today I rebooted my system and upon reboot my LVM wouldnt mount saying "you must specify filesystem". So I tried specifying the filesystem and I got the error "mount: special device /dev/4474/storage does not exist". I am pretty new to LVM so I did some googling and found that pvscan should show my PV's. This returned the following; fileserver:~# pvscan Couldn't find device with uuid 'pvifBp-Fii0-wKCx-gM4m-VxGz-Q6Ee-oyNKL4'. Couldn't find device with uuid 'pvifBp-Fii0-wKCx-gM4m-VxGz-Q6Ee-oyNKL4'. Couldn't find device with uuid 'pvifBp-Fii0-wKCx-gM4m-VxGz-Q6Ee-oyNKL4'. PV /dev/hda2 VG 4474 lvm2 [18.18 GB / 18.18 GB free] PV /dev/hdb VG 4474 lvm2 [74.52 GB / 74.52 GB free] PV /dev/hdc VG 4474 lvm2 [74.52 GB / 74.52 GB free] PV unknown device VG 4474 lvm2 [74.52 GB / 74.52 GB free] Total: 4 [241.75 GB] / in use: 4 [241.75 GB] / in no VG: 0 [0 ] the "unknown" device is /dev/hdd. When I have a look at /dev/hdd using pvdisplay it shows the following. fileserver:~# pvdisplay /dev/hdd --- Physical volume --- PV Name /dev/hdd VG Name 4474 PV Size 74.52 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 19078 Free PE 19078 Allocated PE 0 PV UUID pvifBp-Fii0-wKCx-gM4m-VxGz-Q6Ee-oyNKL4. I really have no idea where to go from here. Thanks to anyone that responds. I'll keep the mailing list updated for archiving purposes.
