Am i right in my assumption that hardware Raid 5 on a Debian box is going to be "better" then Software? And by better would it just be faster? more robust? Some other way? And how much better would it be? Enough to justify the price of a Hardware raid card?

Yea, i've decided to go with Software raid, i have since discovered that decent hardware raid cards cost a loving arm and a leg.

Ok, so i have 3 750GB harddrives in my computer. I wanted to use mdadm to make a software raid5 with these. So i issused this command... mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sda1 /dev/sdc1 /dev/sdd1 When i do mdadm --detail /dev/md0 The state says: clean, degraded, recovering And it says Active Devices: 2 Working Devices: 3 Failed Devices: 0 Spare Devices: 1 Then it lists the 3 harddrives, 0 and 1 stat says active sync, but number 3 says spare rebuilding for state. Did i screw something up, i thought the "spare" option was for a hotspare, but in a raid5 with 3 disks there shouldn't be a hot spare should there be?

IOwnCalculus posted:That's normal - it's effectively treating it as a 3-disc array that you've added the third disc to be rebuilt with. Once it finishes it will move to 3 active and clean. Ok thanks, that's what i was hoping it was doing, but being unsure i figured id ask so that i don't let this thing run for hours (god drat it takes forever) and then find out it was wrong.

We're looking to build a file-server that has basic user/group permissions, afp/smb/ftp/rsync support. I've installed FreeNAS on a test box and it seems to run really well. Setting up the initial users and permissions might be a bit of a pain in the rear end, but overall, it seems to do everything that we require and it's free. I've never really used FreeNAS, but what's wrong with just using A Linux Distro and installing samba?

roflsaurus posted:With a linux software raid array, how would I go about re-installing the base os? if i had a separate IDE OS drive, and a 3 750gb SATA drives in RAID-5, could I just reformat the IDE drive, re-install linux and it would pick up the raid like it was already there, or do I have to issue some commands to mount it? I have this exact setup, debian installed on a 250GB IDE and a software raid5 done with mdadm of 3 x 750 GB SATA drives. I also just yesterday resintalled Debian. All i did was format and reinstall back onto the OS drive, leaving the 3 750gb drives alone, then once i was back in the os, apt-get install mdadm, and it detected and rebuilt /dev/md0 on its own, then it was just a matter of adding a line to fstab.

I'm toying with finally switching my home File Server over to use ZFS. My main question is what the gently caress version of solaris do i want? Solaris 10? OpenSolaris? Solaris Express? Nexenta? (which looks really neat since i come from a Debian server)

OpenSolaris Requires a Keyboard attached? At all times?

I think the official recommendation for ZFS is multiple raidz(2)'s in a pool instead of one big raidz(2) anyways. I might be wrong on that but i am pretty sure that is what sun recommends, and how they have the thumper configured.
