Hi,

it's local storage, 16Gb SAN, Unity 500 storage, all data is on SSD
disks, and file system is JFS2 (mount options are rw,log=INLINE).

Good point about the flags, but we don't have access to the servers,
so not sure if it will be possible to retrieve strace information.
I'll try asking.

Thanks,
Christoph
