Hi everybody,
while trying to figure out what on earth has been going on
in my u20m2 due to
6636511 u20m2 bios version 1.45.1 still can't distinguish disks on sata
channel #1,
I engaged in a lot of cable swapping operations for the internal
sata drive cables.
Somehow I've managed to end up
Hi,
I've seen/read a number of articles on the net, about RAIDZ - and things
like Dynamic Striping et'al. I know roughly how this works - but I can't
seem to get to the bottom of expanding existing pool space, if this is even
possible.
e.g. If I build a RAIDZ pool with 5 * 400Gb drives, and

Hi Karl,
You can't
USB2 giving you ~30MB/s is normal... a little better than mine (on Windows -
~25MB/s) actually.
For better performance better switch to eSATA or Firewire. Even FW400 will give
you better results than USB as there are lesser overheads.
However, I'm sure I saw some FW+ZFS related bug in bugdb
I did some work over the weekend. Still is having some trouble.
# fdisk -E /dev/rdsk/c7t0d0s2
# zpool create Radical-Vol /dev/dsk/c7t0d0
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c7t0d0s0 is part of exported or potentially active ZFS pool
Radical-Vol.
Ok, i have proposed, so, i'm trying to implement it. :)
I hope you can (at least) criticizing it. :))

Apparently I spent more than my brain wanted me to believe. Here is what I
picked up. Even though I am over the 1 meter limit on SATAII, it worked great.

If you care enough to do backups, at least care enough to be
able to restore. For my home backups, I use portable drives with
copies=2 or 3 and compression enabled. I don't fool with
incrementals, but many people do. The failure mode I'm worried
about is decay, as the drives will be

Hello Jorgen,
Honestly - I don't think zfs is a good solution to your problem.
What you could try to do however when it comes to x4500 is:
1. Use SVM+UFS+user quotas

Maybe just use Solaris Volume Manager with Soft Partitioning + UFS and
forget about ZFS in your case?
Well, the idea was to see if it could replace the existing NetApps as

Tape drives and tapes seem to be just too expensive. Am I out of date here?
No, I don't think so. The problem is that the low-end tape market has mostly
vanished as CDs/DVDs/disks get cheaper -- not that it should, because tape is
much more reliable -- so the cost of entry is pretty high. I
Hello All;
While sometimes not possible, ZFS+Thumper solution is not so far away from
replacing expensive to buy and own NetApp like equipment.
What people can sometimes forget is Thumper and Solaris are general purpose
products that can be spcialized with some efforts.
