(Correct me if I'm wrong, but) grub support only matters if /boot is on ZFS. If /boot is (say) ext2 and / is ZFS, then it should be fine providing the ramdisk supports ZFS.
quite likely. i haven't cared enough about root-on-zfs to find out :) hmmm. having boot on ext2 would partly defeat the benefit of having root on zfs. you don't get to give the entire disk to zfs (needed for zfsonlinux to disable barriers)
SSDs are down to about $1/GB now, about half what they were when i got the 120GB SSD for that server, so i'd probably use a 240GB today. or maybe two 120GBs.
Hm, not quite there yet (sans sales):
$ msy | LC_ALL=C w3m -dump -T text/html | foldr egrep -- 2.5 [0-9]+G SSD SATA | sort -nk3 -t'|' [...]
check their parts.pdf - last one i downloaded on 29/6 had Sandisk SSD G25 120GB for $129, 240GB for $249, and 480GB for $489. just fetched the latest - today's PARTS.PDF has them for: Sandisk SSD Extreme 120G / 240G / 480G $129 / $240 / $480 i googled the brand & model number and found a few fairly good reviews of them. also spotted in today's pdf that they have OCZ Agility3 120GB & 240GB models for about $0.90/GB. OCZ Agility3 SATA3 60G / 120G / 240G $65 / $109 / $209 craig -- craig sanders <cas@taz.net.au> BOFH excuse #376: Budget cuts forced us to sell all the power cords for the servers.
