This means you have 3 semaphore sets, of one semaphore each. > > ------ Message Queues -------- > key msqid owner perms used-bytes messages > Also the rest is moderate usage. > # cat /proc/sys/kernel/sem > 250 32000 32 128 So you are far from the maxima (250 per set, 32000 total, 128 sets). > > > Do you see anything in this output? > I have no clue how to interpret this... See e.g. http://man7.org/linux/man-pages/man5/proc.5.html Is the above on a node? engine? both nodes are similar? If so, that's not the reason for the "no space left on device". If this error is reproducible, you can try to find the process that this happens to (perhaps libvirtd, vdsmd, or the hosted-engine ha daemon) and do: strace -f -o /tmp/trace1 -tt -s 512 -p PID where PID is the pid of that process, then search /tmp/trace1 for 'no space left on device' and see the exact call that failed. -- Didi _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
