Hi!
I have an issue with openvswitch on server.
few month ago had issue with server being inaccessible.
After investigation I found a reason for that.
folder /var is on the disk (HDD RAID)
folder /run is in memory(tmpfs)
symlink //var/run -> /run/
/lsof | grep "var/run"
ovsdb-ser 593 root 15u unix
0x00000000065cc4dd 0t0 12496 /var/run/openvswitch/db.sock
type=STREAM
ovsdb-ser 593 root 16u unix
0x00000000d853813b 0t0 12497
/var/run/openvswitch/ovsdb-server.593.ctl type=STREAM
ovsdb-ser 593 root 18u unix
0x000000004cba3d40 0t0 12544 /var/run/openvswitch/db.sock
type=STREAM
ovs-vswit 641 root 9u unix
0x000000007acb4cf4 0t0 16459
/var/run/openvswitch/ovs-vswitchd.641.ctl type=STREAM
ovs-vswit 641 root 48u unix
0x000000003b097565 0t0 25826
/var/run/openvswitch/ovs-inter.mgmt type=STREAM
ovs-vswit 641 root 49u unix
0x00000000a1bb850e 0t0 25827
/var/run/openvswitch/ovs-inter.snoop type=STREAM/
During heaving IO to disk folder /var becomes frozen. ls -l will not
return anything.
since /var contains "run" symlink this results in ovs daemons to fail
and virtual switch stops working.
the solution is to move all pid and sockets to folder /run but is seems
this is hard-coded into ovs daemons.
I've tried to change in conf.db /"rundir","/var/run/openvswitch" /but
ovs will not start after that changes.
