Okay, I tried changing the pv ID but got an error:



$ sudo pvchange -u /dev/md3
Found duplicate PV xny33Ds5AmHaUCNkeJRt7NkD879l4kNV: using /dev/md1 not /dev/md3
Unable to find /dev/md3 in...

Thanks. I did that and then I got this error:



$ sudo mount /dev/md3 /temporary
mount: unknown filesystem type 'LVM2_member'


I typed sudo pvdisplay and it shows a conflict.

Hmmm, didn't like that.



$ sudo mount -t ext4 /dev/sdb6 /temporary
mount: wrong fs type, bad option, bad superblock on /dev/sdb6,
missing codepage or helper program, or other error
...

Is there a way around this?



$ sudo mount /dev/sdb6 /mnt
mount: unknown filesystem type 'linux_raid_member'

Thanks again SaturnusDJ. Not being a UNIX admin expert, what would be the simplest way to mount those and then zero-superblock them?

Thanks SaturnusDJ. Sadly, I'm not sure there was any logic when I created it. It was my first time doing so. I wanted a small RAID 1 for the boot partition. I also wanted a larger RAID 5 for my data....

Here's the output for smartctl -a /dev/sdc

Here's the output for the examine commands. I ran it in this order: sda1, sda5, sda6, sdb1, sdb5, sdb6, sdc1, sdc5, sdc6.249082

Thanks for your reply. Attached is the output for the S.M.A.R.T. tool. Output is in the following order: sda, sdb, sdc. Appears to have found two errors with sdc.

Hi all,

I'm seeing some strange issues with my Ubuntu machine. I have several raid arrays, two RAID 1s and one RAID 5. Recently it has been booting in degraded mode, why I'm not sure. Each time I...

Yeah, that had me scratching my head too. Then I realized that when I was first trying to figure this out I had tried to add sda5 and sda6 to md0. Turns out they were still on that array as spares....

I've also tried re-adding the dev

$ sudo mdadm --manage --re-add /dev/md1 /dev/sda5
mdadm: Cannot open /dev/sda5: Device or resource busy

Hi all,

I have two raid 1 arrays and another raid 5 array. I reboot my computer recently and on boot I saw an LVM error. It appears my raid array wasn't build correctly. Here's what I see in dmesg...

Hi all,

I have three 1 TB drives on my Ubuntu machine that I was using in a RAID 5 array. I had 50 GB on each that I arranged in a logical partition that I used for the base installation. The...

Hi all,

I need to buy an external hard drive that i want to hook up to my ubuntu box. Do they all work with Ubuntu equally well? From what i can tell Ubuntu seems to work with everything very well...

So upgrading did seem to work. Amazing! Thanks!

Fair enough, but do we think this is the source of the problem?

Hi all,

I'm having trouble getting MPD to work. I first tried following the Ubuntu Community page for MPD. I then moved on to the MPD wiki. But neither has helped. I feel like I'm missing...

I'm not sure if this is helpful but I've set mpd to verbose mode and I see this when I start it up:

Hmmm. I put a file in my /var/lib/mpd/music/ directory. Assigned it the owner mpd and group audio. And it still won't play. Sonata loads it like it's about to play it and then it stops. Bizarre.

I can definitely play music from the Samba server on the server with MPD so I don't think that's a problem. I would think that if MPD was trying to create files it would do so in the normal MPD...

Hi all,

I am trying to set up MPD on a server in my basement hooked up to the home intercom so I can play music throughout the house from any computer in the house. Since the computer in the...

Hoping someone has some experience with resizing LVM partitions in a RAID configurations

Thanks Rick. If anyone has experience resizing logical volumes on a RAID partition, I'd be much obliged.
