[zfs-discuss] Mixing RAID levels in a pool

2008-06-07 Thread Fu Leow
Hi, I had a plan to set up a zfs pool with different raid levels but I ran into an issue based on some testing I've done in a VM. I have 3x 750 GB hard drives and 2x 320 GB hard drives available, and I want to set up a RAIDZ for the 750 GB and mirror for the 320 GB and add it all to the same

[zfs-discuss] zfs create or normal directories

2008-06-07 Thread Dick Hoogendijk
I'm quite new to ZFS. It is so very easy to create new filesystems using zfs create zpool/fs that sometimes I doubt what to do: create a directory (like on ufs) or do a zfs create.. Can somebody give some advise on -when- to use a normal directory and -when- it is better to create a

Weird. I have no idea how you could remove that file (beside destroying the entire filesystem)... One other thing I noticed: NAMESTATE READ WRITE CKSUM rpool ONLINE 0 0 8 raidz1ONLINE 0 0 8 c0t7d0 ONLINE

c1t5d0 was part of a mirror but with c1t4d0 removed it now appears as a single drive. Is there a way to recover from this by recreating the mirror with c1t4d0? Detaching a drive from a two-way mirror effectively breaks it up and turns it into a single drive. That's normal. Just attach it back

Re: [zfs-discuss] Filesystem for each home dir - 10,000 users?

2008-06-07 Thread Mattias Pantzare
The problem with that argument is that 10.000 users on one vxfs or UFS filesystem is no problem at all, be it /var/mail or home directories. You don't even need a fast server for that. 10.000 zfs file systems is a problem. So, if it makes you happier, substitute mail with home directories.

For the cifs side of the house, I think it would be in Sun's best interest to work with a third party vendor like NTP software. The quota functionality they provide is far more robust than anything I expect we'll ever see come directly with zfs. And rightly so... it's what they specialize in.
