| mercutio | maybe linux needs something like android permissions
applications can write to their own directory, can write to network etc etc. | [14:48] |
| staticsafe | SELinux | [14:49] |
| mercutio | does that do it?
does steam support it? | [14:49] |
| staticsafe | SELinux can do that yeah, Steam probably doesn't support it | [14:49] |
| mercutio | "selinux prevents steam from starting up" | [14:50] |
| staticsafe | heh | [14:50] |
| mercutio | the alternative is to not use steam at all | [14:50] |
| staticsafe | SELinux is really hard to configure properly | [14:50] |
| mercutio | damn
ubuntu is doing a bit with apparmor but none of these things seem standardised for external applications | [14:51] |

| RandalSchwartz | more zfs puzzlement
I'm wondering if I can migrate from a classic mirror to a raidz | [15:41] |
| ....... (idle for 31mn) | ||
| 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 | [16:13] |
| 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 ? | [16:21] |
| mercutio | what's zxfer | [16:22] |
| RandalSchwartz | it's a nice wrapper around zfs send/recv | [16:22] |
| mercutio | ahh
you can just do attach to go from one drive to two | [16:22] |
| RandalSchwartz | so zroot2/zroot is a clone of zroot | [16:22] |
| 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 | [16:23] |
| 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 | [16:25] |
| mercutio | i see, and then you need to make it bootable. | [16:25] |
| RandalSchwartz | I should probably simulate all this in a virtualbox :) | [16:25] |
| mercutio | are you going from hard-disk to ssd? | [16:25] |
| RandalSchwartz | yes | [16:25] |
| mercutio | 2 hard-disks to 3 ssds? | [16:26] |
| RandalSchwartz | 2 hard disks to 2 ssds | [16:26] |
| mercutio | oh i thought you were talking about raidz | [16:26] |
| RandalSchwartz | yes. raidz works just fine with two drives
better than mirroring :) raidz2 needs three drives | [16:26] |
| mercutio | how's it better than mirroring? | [16:26] |
| RandalSchwartz | no write hole | [16:26] |
| mercutio | huh? | [16:26] |
| RandalSchwartz | .. http://raid-recovery-guide.com/raid5-write-hole.aspx | [16:27] |
| mercutio | raid1 doesn't have write hole | [16:27] |
| RandalSchwartz | they disagree | [16:28] |
| *** | technoid_ has quit IRC (Quit: (null)) | [16:28] |
| 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/ | [16:29] |
| RandalSchwartz | ahh... I might have been misled then | [16:33] |
| 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 | [16:33] |
| RandalSchwartz | that's just to make sure the bootloader knows about zfs
not sure why that's not the default maybe it is now | [16:40] |
