[OpenIndiana-discuss] Newbie server testing...

[John Doe]

Hi,


I am a brand new SunOS/OpenIndiana newbie coming from Linux...
I am trying to build a test storage server for some zfs fun.
First, I would like to know if what I did looks ok, and then I ran into 
a little issue.

So, the server has 6 internal 3TB SATA drives (c5txdy),
plus 2 small eSATA external drives (c3txdy).
I installed the server/text version on the 1st external drive.
Then I more or less did the following:
  pkg update
  reboot
  zpool upgrade rpool
  format -e c3t1d0
    fdisk
    label
    format
  prtvtoc /dev/rdsk/c3t0d0p0 | fmthard -s - /dev/rdsk/c3t1d0p0
  zpool attach -f rpool c3t0d0s0 c3t1d0s0
  installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c3t1d0s0
  zpool create VOLUME raidz2 c5t0d0 c5t1d0 c5t2d0 c5t3d0 c5t4d0 c5t5d0
So, I have a RAID1 on the 2 external drives, and a RAID6 on the 6 internal.
Anything wrong or inefficient?
I read about putting zfs logs out of the RAID6, but not sure how...
I think the format part is a bit unclear for me but it worked...

Then, for testing, I needed to put some data from an ext3 usb drive on 
the raidz2... So I had to first install ext2 support:
  pfexec pkgadd -d SFEe2fsprogs.pkg SFElibiconv SFEe2fsprogs
  pfexec pkgadd -d SUNWext2fs.pkg SUNWext2fs
It worked, but the file transfer (rsync -avH) was VERY slow (only 179G in 15 hours)...
From the logs:

And that stops there at 3am because this morning I had been disconnected 
and when I went to the server, there was some kind of "kernel" panic (I 
think related to ext2fs) and it said something about dumping zfs stuff and 
rebooting... but it got stuck there and never rebooted.
I cannot find the panic message... is it written somewhere or only on the 
screen?
Is the ext2fs module stable?

Thx,
JD
