[zfs-discuss] Drive Checksum error

2008-12-16 Thread Glaser, David
Hi all, A few weeks ago I was inquiring of the group on how often to do zfs scrubs of pools on our x4500's. Figures that the first time I try to do a monthly scrub of our pools, we get one of the three machines to throw an error. On one of the machines, there's one disk that has registered one

[zfs-discuss] How often to scrub?

2008-12-01 Thread Glaser, David
Hi all, I have a Thumper (ok, actually 3) with each having one large pool, multiple filesystems and many snapshots. They are holding rsync copies of multiple clients, being synced every night (using snapshots to keep 'incremental' backups). I'm wondering how often (if ever) I should do scrubs

Re: [zfs-discuss] zvol snapshot at size 100G

2008-11-12 Thread Glaser, David
Are you asking if zvol size is 100GB can you do a snapshot of it, or can the snapshot grow to over 100GB? I have a x4500 with nightly snapshots being done on a 7 terabyte filesystem (each nightly snapshot is about 20GB). I don't believe there is a functional limit to the size of the snapshot

2008-10-09 Thread Glaser, David
As shipped, there our x4500 have 8 raidz pools with 6 disks each in them. If spaced right, you can loose 6(?) disks without the pool dying. The root disk is mirrored, so if one dies it's not the end of the world. With the exception that grub is thoroughly fraked up in that if the 0 disk dies,

[zfs-discuss] disk UNAVAIL

2008-09-03 Thread Glaser, David
I have a disk that went 'bad' on a x4500. It came up with UNAVAIL in a zpool status and was 'unconfigured' in cfgadm. The x4500 has a cute little blue light that tells you when it's able to be removed. With it on, I replaced the disk and reconfigured it with cfgadm. Now cfgadm lists it as

When you say 'removing a disk' from a zpool, do you mean shrinking a zpool by logically taking disks away from it, or just removing a failing disk from a zpool? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Polombo Sent: Wednesday, August 20,

We had the same problem, at least a good chunk of the zfs volumes died when the drive failed. Granted, I don't think the drive actually failed, but a driver issue/lockup. A reboot 2 weeks ago brought the machine back up and the drive hasn't had a problem since. I was behind on two patches that

Hi all, I'm a little (ok, a lot) confused on the whole zfs send/receive commands. I've seen mention of using zfs send between two different machines, but no good howto in order to make it work. I have one try-n-buy x4500 that we are trying to move data from onto a new x4500 that we've

Hi all, I'm new to the list and I thought I'd start out on the right foot. ZFS is great, but I have a couple questions I have a Try-n-buy x4500 with one large zfs pool with 40 1TB drives in it. The pool is named backup. Of this pool, I have a number of volumes. backup/clients
