Opensolaris

used to run it on my main machine at home, now i run it as a xen guest. kernel updates are a little tricky with a linux host, so here is a small script to facilitate. this is to be run on the domU. change “unixfile” to point to the 32bit or 64bit platform (at this time, i’m having trouble running the 64bit platform, so it’s pointed at 32bit).

update_dom0

#!/bin/bash

dom0=10.0.1.23
dompath=/var/lib/xen/kernels/push
unixfile=/platform/i86xpv/kernel/unix

root=`pfexec beadm list -H | grep ';N*R;' | cut -d \; -f 1`
mkdir /tmp/root
pfexec beadm mount $root /tmp/root 2>/dev/null
mount=`pfexec beadm list -H $root | cut -d \; -f 4`
pfexec bootadm update-archive -R $mount
scp $mount/$unixfile root@$dom0:$dompath/kernel.$root
scp $mount/platform/i86pc/$3/boot_archive root@$dom0:$dompath/ramdisk.$root
pfexec beadm umount $root 2>/dev/null
echo "Kernel and ramdisk for $root copied to $dom0:$dompath"
echo "Kernel cmdline should be:"
echo "$unixfile -B zfs-bootfs=rpool/ROOT/$root,bootpath=/xpvd/xdf@51712:a"

arcstat

here’s a small perl script to peek at what the ZFS ARC is doing, pulled from http://www.solarisinternals.com/wiki/index.php/Arcstat originally: Attach:arcstat.pl

zfs meet cifs

mostly cribbed from genunix

  • install the package service/file-system/smb (formerly SUNWsmbs/SUNWsmbskr)
  • enable the service: svcadm enable -r smb/server
  • optionally join a workgroup: pfexec smbadm join -w labs
  • add the following line to PAM so CIFS passwords will be generated by the system: other password required pam_smb_passwd.so.1 nowarn
  • passwords will need to be updated or reentered after the above line is added before they will work for CIFS auth
  • set the sharesmb property on a given zfs filesystem. good to go.
