I have a Supermicro server with an Adaptec 2020SA RAID card and RAID10 setup. This server is mainly used as an NFS host for VMware data storage of VM's. I have been having the following issue locking up the server.... aacd0: COMMAND 0xffffffff808599e0 TIMEOUT AFTER XXXX SECONDS I reboot, clean the partitions in single user mode and all comes back up fine. After some searching, I found that it could be the card or perhaps I should disable soft updates using tunefs. I verified the partitions do have soft updates enabled except for the root partition. There is one /data partition that serves the VM's to VMware and it has soft updates enabled as well as the /usr and /var partitions. Does anyone have any experience with doing this or whether disabling soft updates on one or more of these partitions is a good idea, what effects it would have for this type of usage for the server? Also, if I replace the RAID card, does anyone know if the RAID is lost when doing so or it should recognize the existing RAID setup? Thanks -- Robert
