Re: [zfs-discuss] resizing a ZFS filesystem
Increasing is not that problem. ZFS does it automatically. Change the size of a partition or replace a disk with a bigger one and it will use the newly available space. -- Ted Turner - Sports is like a war without the killing. - http://www.brainyquote.com/quotes/authors/t/ted_turner.html ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Re: Best use of 4 drives?
Hi Rick, Hmm. Not sure I can do RAID5 (and boot from it). Presumably, though, this would continue to function if a drive went bad. It also prevents ZFS from managing the devices itself, which I think is undesirable (according to the ZFS Admin Guide). I'm also not sure if I have RAID5 support in the BIOS. I think it's just RAID0/1. Just a mainboard BIOS RAID is only like a software raid - accept that you may can't get your data back if the RAID-controller die ... and when, you'll need the same hardware again. So you may want to use a software-RAID instead of a plugin-card which supports buffering the read/write operations on power lost - it is nearly the same as when you use your BIOS (not a RAID-Controller) for that. And I RAID5 you'll able to boot if you have a /boot partition outside the RAID5.

Re: [zfs-discuss] Can you create a degraded raidz vdev?
Hi Paul, I think I have a smiliar problem, I have 4 disks, two empty, two full and want to create a RAIDZ1 from these disk. But I'm new to zfs, maybe you can explain me how do you done it, if it runs :) Thanks in advance :) Greetings Cyron I have 6 400GB discs and want to make two RAIDZ 2/1 vdevs out of them (ie 2stripe 1parity). The problem is that 4 are in use... so I want to do something like: zpool create datadump raidz c1t0d0 c1t1d0 missing Then move and bunch of data into datadump, to free up another two discs, then zpool add datadump raidz c1t2d0 c1t3d0 missing Now move the rest of the data over, freeing the last two drives which I would then add as spares to let zfs complete the parity of those vdevs. signature.asc Description: PGP signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Best use of 4 drives?
Hi Rick, what do you think about this configuration: Part all disks like this 7GiB 493GiB Make a RAIDz1 out of the 493GiB partitions and a RAID5 out of the 7GiB partitions. Create a swap, and the root in the RAID5, the dirs with the user data in the ZFS storage. Backup the / daily to the ZFS :) Greetings Cyron I'm putting together a NexentaOS (b65)-based server that has 4 500 GB drives on it. Currently it has two, set up as a ZFS mirror. I'm able to boot Nexenta from it, and it seems to work ok. But, as I've learned, the mirror is not properly redundant, and so I can't just have a drive fail (when I pull one, the OS ends up hanging, and even if I replace it, I have to reboot. I asked about this on the Nexenta list: http://www.gnusolaris.org/phpbb/viewtopic.php?t=6233). I think the problems stem from limitations in booting from ZFS. So, I'm going to re-do the drive allocations, but I'm not sure the best way to go. I'm hoping this list will give me some advice. I was thinking I'd put the basic OS on one drive (possibly a ZFS pool), and then make a RAID-Z storage pool from the other three drives. The RAID-Z pool would contain filesystems for /usr, /home, etc. The drawback to this approach is that a 500 GB drive is far too large for the basic OS, and seems to end up wasted. An alternative would be to partition one drive, give it 20 GB for the OS and the rest for use by ZFS to allocated to a storage pool, but at this point ZFS isn't working with the raw device, and so I'm not sure what limitations this may place on me. BTW, I don't mind if the boot drive fails, because it will be fairly easy to replace, and this server is only mission-critical to me and my friends. So...suggestions? What's a good way to utilize the power and glory of ZFS in a 4x 500 GB system, without unnecessary waste? Thanks much!
