hi,
we're running FreeNAS-9.2.1.7-RELEASE-x64
what began as a pilot test has been working well, so as often happens more writers are using this (nfs mostly 1 cifs, no iscsi) and the original drives we used for some of our roles (slog, l2arc) we'd like to change.
namely:
* slog is currently a 160GB intel s3500 SSD.
* L2ARC is striped across a few crucial mlc SSDs
I'd like to retire the multiple crucials** and simply have 1 L2ARC (the current slog drive: the 160GB s3500) as it would seem to be plenty big based on historical usage (this is a heavy write filer, very few common reads, just confirming writes really).
I'd like to put in an intel s3710 for our new SLOG.
scheduled maintenance is fine, ideally we'd stop nfs and dismount what needs doing and remove the current L2ARC drives, remove the slog, retask slog to be new L2ARC and insert new SLOG and assign it that role. Have you done this? any steps/guides you can share?
** also, our filer locked up and upon boot i saw a warning fly by in the messages about this crucial drive(s) possibly/likely (?) locking up every 51xx hours. they're spare crap drives, i'd rather remove them from this system which has become more important to us.
also, regarding updating firmware of the s3500 after it's no longer SLOG and before it's the new L2ARC - easy to do in freenas?, or should i just pull it from the chassis during this window and update via usb/sata connector on my laptop while at datacenter?
in case it matters:
'head' node is a dell r710 server, original Perc removed -- an IT firmware flashed IBM 105 HBA connects to dell server backplane, all these 2.5" drives are in hot swap trays. OS drive is another 160GB s3500. actual ZFS drives are all in external supermicro JBOD, connected via a 2nd HBA in our 'head', an LSI 9200e with dual 8088 out the back, reflashed to IT mode, no boot bios. we have four x 6 drive raidz2 vdevs in our one vol
