[slurm-users] Cluster not booting after upgrade to debian jessie

Root file system is on the master. I'm being able to boot the machine
changing kernel. Grub allow to boot from two kernel:

kernel 3.2.0-4-amd64

kernel 3.16.0-4-amd64

The problem is with kernel 3.16, but boots correctly with 3.2.

Anyway, rebooting with kernel 3.2, slurm (now updated to 14.03.9, was
2.3.4) doesn't work anymore and gives this error:

First time after reboot launching sinfo:

*sinfo: error: If munged is up, restart with —numthreads=10*

*sinfo: error: Munge encode failed: Failed to access
/var/run/munge/munge.socket2”: No such file or directory*

*sino: error: Authentication: Socket communication error*

*slurm_load_partition: Protocol authentication error*

Re-launching sinfo

*slurm_load_jobs error: Unable to contact slurm controller (connect

What does it mean?


PS: In the kernel 3.16 case, it gives the "gave up waiting" error and
*before* the error is thrown there is another error

"Running scripts/local-block

Unable to find lvm volume"

It keeps trying this thing several times and then falls back to initramfs.
(even if booted in recovery!)

Moreover, in this situation it seems not to load the usb keyboard so i'm
truly able to do anything.
