Re: Promise RAID array and mounting questions
I've been using ZFS for several months now and it's been very good. There were some problems in the beginning which have since been remedied by using info from the following link: http://wiki.freebsd.org/ZFSTuningGuide The setup has is 5 x 320GB drives and 5 x 200GB drives both in RAID-Z configuration and aggregated into 1 pool. There was a PSU failure which destroyed the motherboard/proc running this machine and recovery of the array in a new box was amazingly easy.

You should use gpt instead. Do you want the entire array as one partition? # gpt create /dev/da0 # gpt add /dev/da0 # newfs -O2 -U /dev/da0p1 (or 'newfs -O2 -U -i 524288 /dev/da0p1' if you have mostly multi-megabyte files) If you want multiple partitions you will have to pass a size (in sectors) as a parameter to 'gpt add'. Beware that you might not be able to fsck the filesystem because of its size. I'm not sure how well gjournal handles fsck of large filesystems. Personally I'm going with ZFS for my next large array (8x750GB). /Daniel Eriksson ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

When I have, I defined the array outside FreeBSD. When I installed FreeBSD it saw the array as just a single disk volume, which I partitioned in the sysinstall process. Do you have the array already created? What are you seeing in sysinstall when you go to partition the volume? -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
