[linux-lvm] LVM Broken on boot.

[linux-lvm] LVM Broken on boot.

[Terry Rigby]

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.

Well, I might be somewhere now but I might have also screwed up all my data on 
the device.  I fixed the initial problem and ended up having to basically 
start fron scratch to create the LV again.  I didnt format anything, the only 
thing I did havnt to do with a filesystem was to do resize_reiserfs 
-f /dev/4474/storage.  All went fine except when I try to mount the device. 

mount /dev/4474/storage (setup in my fstab)

mount: wrong fs type, bad option, bad superblock on /dev/4474/storage,
       or too many mounted file systems

:(  Dont know where to go from here

I tried mounting the device manually "mount -t 
reiserfs /dev/4474/storage /storage" and IT WORKED.  It doesnt work without 
specifying the filesystem but at least it works.  I basically removed all 
drives from the lv and removed the info on the drive using pvremove. Then I 
complety restarted from scratch (following the howto at tldp.org) making sure 
I added the devices in the same order as I originally had them.

Thats about all I can offer for advice.  I don't even know if it is dangerous 
to do it this way or not but it worked for me, maybe it will work for someone 
else one day also.
