Thread: Lost Raid Drive on Upgrade


if memory serves me correct, lost same mounted drives last time upgraded.

situation this, have 2 physical drives in mirrored array (md0, md1, md2 /, swap, , /home) mount fine after upgrade. have 2 additional physical drives in mirrored array (md3) not mounting after upgrade.

2 part question, need change them mount on boot? , second, how set things don't have go through everytime upgrade?

best.

edit: after additional searching found post suggested nodmraid flag grub options on boot. raid back. is, more or less, solved. now, if can fix other minor problems - internet connectivity being high priority....

some additional information.

seems /etc/mdadm/mdadm.conf file altered. after upgrade have this:

code:
rob@ubuntu:~$ sudo more /etc/mdadm/mdadm.conf  # mdadm.conf  #  # please refer mdadm.conf(5) information file.  #    # default, scan partitions (/proc/partitions) md superblocks.  # alternatively, specify devices scan, using wildcards if desired.  device partitions    # auto-create devices debian standard permissions  create owner=root group=disk mode=0660 auto=yes    # automatically tag new arrays belonging local system  homehost <system>    # instruct monitoring daemon send mail alerts  mailaddr root    # definitions of existing md arrays  array /dev/md0 level=raid1 num-devices=2 uuid=ed6328ea:6d0415a7:5c63eca1:21758821  array /dev/md1 level=raid1 num-devices=2 uuid=7851030e:d37f7db4:d6a60d57:67baf657  array /dev/md2 level=raid1 num-devices=2 uuid=6b00fc3f:49db5cdd:eaa9c022:e33e0eb6  array /dev/md/d3 level=raid1 num-devices=2 metadata=00.90 uuid=dd80dd73:a6bbbcb6:ca66c3a1:f2e4c2cd    # file auto-generated on fri, 19 sep 2008 06:19:10 +0000  # mkconf $id$
i have tried commenting out line has "/dev/md/d3" since seems out of place , replacing same line "/dev/md3" consistent others. no change. tried removing "metadata=00.90", again, no change.

running blkid gives following:

code:
rob@ubuntu:~$ sudo blkid  [sudo] password rob:   /dev/sda1: uuid="ed6328ea-6d04-15a7-5c63-eca121758821" type="linux_raid_member"   /dev/sda2: uuid="7851030e-d37f-7db4-d6a6-0d5767baf657" type="linux_raid_member"   /dev/sda3: uuid="6b00fc3f-49db-5cdd-eaa9-c022e33e0eb6" type="linux_raid_member"   /dev/sdb1: uuid="ed6328ea-6d04-15a7-5c63-eca121758821" type="linux_raid_member"   /dev/sdb2: uuid="7851030e-d37f-7db4-d6a6-0d5767baf657" type="linux_raid_member"   /dev/sdb3: uuid="6b00fc3f-49db-5cdd-eaa9-c022e33e0eb6" type="linux_raid_member"   /dev/sdc: type="promise_fasttrack_raid_member"   /dev/sdd: type="promise_fasttrack_raid_member"   /dev/sde1: uuid="66dc5b4b-af90-40fc-91ff-31a4bb3282e4" type="ext3"   /dev/md0: uuid="399c3bcd-5919-4f92-ab60-0340c6ed89f1" type="ext3"   /dev/md1: uuid="6382644c-16aa-4eeb-b04a-964149bfb40d" type="swap"   /dev/md2: uuid="0c469aa8-1384-4499-8dda-63b15ef17231" type="ext3"
the 2 lost drives make md3 in slots /sdc , /sdd.

finally, if open gparted see following drives:

/dev/mapper/pdc_bdgfhji (465.66 gib) - have no idea is. says unallocated.
/dev/sda , /dev/sdb fine
/dev/sdc lists following under information:
code:
file system: ext3  size: 465.76 gib  flags: raid    path: /dev/sdc1  status: not mounted  label:  uuid:    first sector: 63  last sector: 976768064  total sectors: 976768002    warning:  e2label: no such file or directory while trying open /dev/sdc1  couldn't find valid filesystem superblock.    couldn't find valid filesystem superblock.    dumpe2fs 1.41.9 (22-aug-2009)  dumpe2fs: no such file or  directory trying open /dev/  sdc1    unable read contents of file system!  because of operations may unavailable.
/dev/sdd lists similar info.

use insight if has any.

thanks.
