[SOLVED] Jessie with HW RAID

#1 Post by Schnoof »

Hello,

we've just got a new computer having a hardware RAID and decided to install Debian Jessie. We use the recommended partition setup (root, home, var, tmp, swap). We now have the problem that the system always starts in emergency mode. Sometimes it boots without visible errors (only green OKs). Sometimes it cannot mount some or all of the partitions (in this case we of course there are not only green OKs). Every boot is different, it is not fully repeatable.

When we call update-grub it says that it cannot create /var/lib/os-prober/mount. The directory /var/lib/os-prober/ indeed does not exist, but the package os-prober is installed.

What can we do to solve our problem?

What makes you think you have hardware RAID?

Required reading.

If you really have hardware RAID, what model?

It actually is what I was told.

What I can see is:
We have a IMB-M43 motherboard
Serial ATA: 6x SATA 6.0 Gb/s connectors
Software RAID support 0/1/5/10
We have 2 hard disks

The problem is solved.

The one who installed used an older tutorial (https://wiki.debian.org/DebianInstaller/SataRaid). It says to change /etc/fstab for swap to UUID. Since systemd it seems that swap is mounted automatically so this is not needed anymore. We commented out this line now. All other entries were also changed to UUID. Now we changed the entries to /dev/dm-x and it simply works and successfully boots.

You should have used mdraid instead. It was in that article you neglected to read.

I cannot read what I cannot open. There are many useful websites blocked and I have to confine myself to those not blocked.
