Hi. If I create a zpool with the following command: zpool create tank raidz2 da0 da1 da2 da3 da4 da5 da6 da7 and after a reboot the device names for some reason are changed so da2 and da5 are swapped, either by altering the LUN setting on the storage or by switching cables/swapping disks etc.? How will zfs handle that? Will it simply acknowledge that all devices are present and the pool is intact an...

Hi All, I am looking at ZFS and I get that they call it RAIDZ which is similar to RAID 5, but what about RAID 10? Isn''t a RAID 10 setup better for data protection? So if I have 8 x 1.5tb drives, wouldn''t I: - mirror drive 1 and 5 - mirror drive 2 and 6 - mirror drive 3 and 7 - mirror drive 4 and 8 Then stripe 1,2,3,4 Then stripe 5,6,7,8 How does one do this with ZFS?

Hi all Having managed ZFS for about two years, I want to post a wishlist. INCLUDED IN ZFS - Mirror existing single-drive filesystem, as in ''zfs attach'' - RAIDz-stuff - single and hopefully multiple-parity RAID configuration with block-level checksumming - Background scrub/fsck - Pool-like management with multiple RAIDs/mirrors (VDEVs) - Autogrow as in ZFS autoexpand NOT

Hi. I''m all set for doing performance comparsion between Solaris/ZFS and FreeBSD/ZFS. I spend last few weeks on FreeBSD/ZFS optimizations and I think I''m ready. The machine is 1xQuad-core DELL PowerEdge 1950, 2GB RAM, 15 x 74GB-FC-10K accesses via 2x2Gbit FC links. Unfortunately the links to disks are the bottleneck, so I''m going to use not more than 4 disks, probably.

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
