[zfs-discuss] Consequences of resilvering failure

2010-07-06 Thread Michael Johnson
I'm just about to start using ZFS in a RAIDZ configuration for a home file server (mostly holding backups), and I wasn't clear on what happens if data corruption is detected while resilvering. For example: let's say I'm using RAIDZ1 and a drive fails. I pull it and put in a new one. While res

2010-07-10 Thread Michael Johnson
I'm planning on running FreeBSD in VirtualBox (with a Linux host) and giving it raw disk access to four drives, which I plan to configure as a raidz2 volume. On top of that, I'm considering using encryption. I understand that ZFS doesn't yet natively support encryption, so my idea was to set e

[zfs-discuss] Recommended RAM for ZFS on various platforms

2010-07-16 Thread Michael Johnson
I'm currently planning on running FreeBSD with ZFS, but I wanted to double-check how much memory I'd need for it to be stable. The ZFS wiki currently says you can go as low as 1 GB, but recommends 2 GB; however, elsewhere I've seen someone claim that you need at least 4 GB. Does anyone here
