BTRFS multi-disc persistent mount?

Alethos · 2010-07-26 23:08:22

How do you make a raid10 btrfs ... ah ... pool, I guess is the right word, persistent? After a reboot I have to

btrfsctl -a

then

mount -U 11d8ccf8-0eb4-4787-94ba-ff5e1fb508ef /thulcandra-extra

Would be preferable to have it mount at boot but when I tried putting the mount line in fstab it complained.

Putting both commands in /etc/rc.local works. One should not need to do that of course. Could you write a bug report?

Alethos · 2010-07-28 15:26:03

Is it simply not possible (at this point)?

From the BTRFS wiki:
After a reboot or reloading the btrfs module, you'll need to use btrfsctl -a to discover all multi-device filesystems on the machine.

then it goes on to give the command I listed previously (btrfsctl -a).

Perhaps it's not a bug...it's a feature! Won't auto load (w/out intervention as you mention) for file checking purposes or somesuch?

Aedit · 2010-07-28 15:57:02

Can't think of any advantage, or any good reason the device discovery had not been done before fstab except the novelty of btrfs. The question now is what is the most appropriate way to run the "btrfsctl -a".

Likely its a similar reason that multi device discovery doesn't "just happen" in the case of LVM or RAID. Feel free to add "btrfs" to your hooks in mkinitcpio. This was added in mkinitcpio 0.6.7 and simply runs 'btrfsctl -a' at boot.

If you want to boot off this device, you'll need a more advanced btrfs hook

Nice there is a hook now, I hadn't looked at this for a while. The hook happens before rc.sysinit, which is OK, but you might not have all the devices to scan until the middle of rc.sysinit.

I don't follow. If you're missing a device that you need at early on, add the appropriate modules to your initcpio so that you do have it before rc.sysinit.

Alethos · 2010-07-28 22:33:48

Added btrfs to mkinitcpio.conf hooks line before filesystems (as in the wiki example lvm was before, not sure if placement within the hook line matters)

HOOKS="base udev autodetect pata scsi sata btrfs filesystems"

rebuilt image

sudo mkinitcpio -p kernel26

added mount to fstab

UUID=11d8ccf8-0eb4-4787-94ba-ff5e1fb508ef /thulcandra-extra btrfs gid=101 0 0

Still, boot complains (wrong fs or bad superblock msg - same as before). However, I tried to manually mount the FS and as a test I tried w/out running btrfsctl -a first and lo and behold it mounted. So the hook is working, just not before the FS is mounted at boot.

falconindy · 2010-07-28 22:54:53

Well, order does matter but in this case I think you're safe. However, I'm suspicious that the correct modules are being added. Merge the following into your MODULES in mkinitcpio.conf:

btrfs
libcrc32c
crc32c
zlib_deflate

Regenerate, reboot. If this works, a bug report is in order.

Alethos · 2010-07-28 23:12:09

Added modules to mkinitcpio.conf

MODULES="btrfs libcrc32c crc32c zlib_deflate"

regenerated sucessfully (by regenerate, I gather you to mean mkinitcpio -p kernel26), rebooted and still same error message

falconindy · 2010-07-28 23:29:27

Could you post your blkid and pastie dmesg?

btrfsctl is failing to find anything, and I'm not sure why. You should be seeing discovered drives. Something like...

Btrfs loaded
device label Gluttony devid 1 transid 75112 /dev/sdd1
device label Entropy devid 1 transid 5009 /dev/sdb4
device label root devid 2 transid 20801 /dev/sdb3
device label root devid 1 transid 20801 /dev/sda2
device label root devid 1 transid 20801 /dev/disk/by-uuid/254d2593-b402-42be-8a18-9dc5cc64c18

Anything peculiar about these drives, or are they just your average run of the mill internal disks? Perhaps try the other hook from the AUR? I'm running out of ideas...

Aside: Am I really seeing that blkid correctly? You fed entire drives, without partitioning to mkfs.btrfs?

Run of the mill disks, yep. WD green tb's. btrfs loads a smidgin before the devices are listed in dmesg, could this be the issue as Aedit mentioned or are those modules you had me load good enough?

You are reading that correctly, i fed entire devices, no partitioning. This is the first I've messed with any type of raid. I didn't know if partitions were necessary if the whole drive was going to be used. I followed the btrfs wiki for multi-drive setups, their example is whole devices, not partitions.

# Create a filesystem across four drives
mkfs.btrfs /dev/sdb /dev/sdc /dev/sdd /dev/sde

So, to answer your question I did mkfs.btrfs, just not partition level.

A side thought from me...my btrfs raid is spanning 4 drives, wonder why blkid is only showing 3/ once the FS is mounted, it is the proper size for 4 disks.

I'll keep looking online and poking around.

btrfs: unrecognized mount option 'gid=101'
btrfs: open_ctree failed
Adding 4000180k swap on /dev/sde2.  Priority:-1 extents:1 across:4000180k

Maybe fixed the mount option. And how is it possible to use both sde2 and sde?

falconindy · 2010-07-29 15:18:38

Those messages late enough that they're likely being generated by mount -a when called from rc.sysinit. The bad mount option shouldn't prevent the volume from being mounted. The line after is the effect from the failed mount. It's something you see when not all the required modules are loaded for btrfs -- perhaps there's other triggers as well.

The very last line of the log I can only assume is the OP running btrfsctl -a manually.

edit: I'm curious about about the sde2 && sde thing as well now...

In post 16 the code I have is from the btrfs wiki, not necessarily what I have on my machine. sde is my OS drive partitioned out with boot swap and root. sda, b, c and d are the storage drives. Sorry for the confusion.
