classy m0unds: quality BryceBot: That's what she said!! mercutio: maybe linux needs something like android permissions
applications can write to their own directory, can write to network etc etc. staticsafe: SELinux mercutio: does that do it?
does steam support it? staticsafe: SELinux can do that yeah, Steam probably doesn't support it mercutio: "selinux prevents steam from starting up" staticsafe: heh mercutio: the alternative is to not use steam at all staticsafe: SELinux is really hard to configure properly mercutio: damn
ubuntu is doing a bit with apparmor
but none of these things seem standardised for external applications RandalSchwartz: more zfs puzzlement
I'm wondering if I can migrate from a classic mirror to a raidz mercutio: you have to create a new pool
if you want to shift from two drive mirror to 3 way raidz you can disconnect one of the mirrored drives, and create a raidz array with a missing drive afaik
on the other two drives
transfer the data
then take the first disk and put it in
i did raidz to mirrored though so i'm not altogether sure.
from 3 drives to 4, without having enough sata ports for all the drives at once rather than not enough drives.
i'd normally recommend just going to a pair of mirrored drives though
err two pairs
unless it's just bulk storage, and then people tend to want to jump up to raidz2
raidz with 2 3 drive pairs is pretty good though
it's pretty much a major pita doing the transfer RandalSchwartz: so I created zroot2 on my SSDs, and am using zxfer to do the mirror
what's the easiest way to boot off the ssds later?
just edit /boot/loader.conf ? mercutio: what's zxfer RandalSchwartz: it's a nice wrapper around zfs send/recv mercutio: ahh
you can just do attach to go from one drive to two RandalSchwartz: so zroot2/zroot is a clone of zroot mercutio: i see
i don't do zfs root
because i use linux with zfs ;)
in linux you can easily do partitions with zfs
so you can have a separate pool for bootup/system from data
just using beginning of drives
so if shifting from 2 to 3 ssd's, you could just do 3 way mirror.
for systerm, and then raidz for data
ssd's i can understand wanting to do raidz :)
i am pretty sure solaris doesn't support raidz root
you may want to check that freebsd does actualyl support it RandalSchwartz: the probelm is the ssds aren't the same size as the currnt /
so I need to use send/recv to move the data
but then I'm not sure how to get it to boot that mercutio: i see, and then you need to make it bootable. RandalSchwartz: I should probably simulate all this in a virtualbox :) mercutio: are you going from hard-disk to ssd? RandalSchwartz: yes mercutio: 2 hard-disks to 3 ssds? RandalSchwartz: 2 hard disks to 2 ssds mercutio: oh i thought you were talking about raidz RandalSchwartz: yes. raidz works just fine with two drives
better than mirroring :)
raidz2 needs three drives mercutio: how's it better than mirroring? RandalSchwartz: no write hole mercutio: huh? RandalSchwartz: .. http://raid-recovery-guide.com/raid5-write-hole.aspx mercutio: raid1 doesn't have write hole RandalSchwartz: they disagree ***: technoid_ has quit IRC (Quit: (null)) mercutio: well raidz is definitely not designed for two disks
http://blog.pascalj.com/article/migrate-a-freebsd-server-with-a-zfs-root-filesystem/
does that help/ RandalSchwartz: ahh... I might have been misled then mercutio: gpart bootcode -b /mnt/boot/pmbr -p /mnt/boot/gptzfsboot -i 1 ada0
that seems to be the main thing i had no idea about RandalSchwartz: that's just to make sure the bootloader knows about zfs
not sure why that's not the default
