help! volume1 not mounted after reboot
As I added the disk to the raid6 array, after the synchronization was completed, the system stopped mounting /dev/md1 volume1.
root@nas:~ # mdadm --detail /dev/md1
mdadm: cannot open /dev/md1: No such file or directory
root@nas:~ # mdadm --detail /dev/md1
mdadm: cannot open /dev/md1: No such file or directory

Re: help! volume1 not mounted after reboot
Try assembling the array manually or using mdadm --assemble --scan. If that succeed check the md1 UUID that it matches /volume0/usr/etc/volume.conf. Also mount the /dev/md1 to /volume1 then check the UUID in /volume1/.@system/volume.conf.

Re: help! volume1 not mounted after reboot
Is md127 supposed to be your original md1 (volume1)? Show us your `cat /volume0/usr/etc/volume.conf`and `blkid`.

but I'm not sure if the raid recovered correctly.
is it critical if the sequence of disks was different?
before the path was:
/dev/sdb4 /dev/sdh4 /dev/sdc4 /dev/sdg4 /dev/sde4 /dev/sdf4 /dev/sdd4 /dev/sda4
Code: Select all
root@nasl05:/dev # cat /volume0/usr/etc/volume.conf

Re: help! volume1 not mounted after reboot
Ok understood happened to me before but not sure what's the root cause.yes, md127 supposed to be my original md1 (volume1)
Run the command `blkid`.sorry, I don't understand what means blkid
Try below, important: take note it will change your UUID so you'll need to update both the volume.confs:
1. Umount (if not already, `umount /dev/md127`) then stop /dev/md127: `mdadm --stop /dev/md127`.
2. Assemble back: `mdadm --assemble --update=name --name=1 /dev/md1 /dev/sdh4 /dev/sda4 /dev/sdd4 /dev/sdf4 /dev/sde4 /dev/sdg4 /dev/sdc4 /dev/sdb4`.
You can test if it will work without rebooting, stop it `mdadm --stop /dev/md1`, then try auto assemble `mdadm --assemble --scan`.
3. Take note of the md1 UUID: `mdadm -D /dev/md1|grep UUID`.
4. Update the UUID you got from #3 in volume0 using vi, Google how to use vi: `vi /volume0/usr/etc/volume.conf`.
5. Mount the md1: `mkdir -p /volume1 && mount /dev/md1 /volume1`.
6. Update the UUID you got from #3 in volume1: `vi /volume1/.@system/volume.conf`.
Wait for your other resync to complete then reboot to test.

Re: help! volume1 not mounted after reboot
Before there were lines like this:
md1 : active raid6 sdb4[8] sdh4[0] sdc4[6] sdg4[5] sde4[4] sdf4[3] sdd4[7] sda4[1]
Now
md1 : active raid6 sdh4[0] sdb4[8] sdc4[6] sdg4[5] sde4[4] sdf4[3] sdd4[7] sda4[1]
different order disks - sdh4[0] and sdb4[8]
Is this important or do I need to assemble so as not to lose data? It is very important for me

Re: help! volume1 not mounted after reboot
As far as I know the order doesn't matter as long mdadm recognize them correctly. Because the nodes i.e. /dev/sd[a-z] might change when you reboot. So your data is safe.
