New home server arrived

The new server arrived and like a good geek I stayed up late last night putting it together and loading the Solaris Operating System on it. So far I've not got that far. A base install with mirrored root file system, plus a second boot environment for live upgrade and the rest of the disk(s) are there for real data on ZFS.

Laying out the disks was harder than it should have been due to me wanting to put all the non ZFS bits at the end of the disk not the beginning so that when we have a complete ZFS on root solution I can delete the two root mirrors and allow ZFS to grow over the whole drive. So on the disks the vtoc looks like this:

Part      Tag    Flag     Cylinders         Size            Blocks
  0 unassigned    wm   37368 - 38642        9.77GB    (1275/0/0)   20482875
  1 unassigned    wu       0                0         (0/0/0)             0
  2     backup    wm       0 - 38909      298.07GB    (38910/0/0) 625089150
  3 unassigned    wu       0                0         (0/0/0)             0
  4       root    wu   36093 - 37367        9.77GB    (1275/0/0)   20482875
  5 unassigned    wu   38643 - 38645       23.53MB    (3/0/0)         48195
  6 unassigned    wu   38646 - 38909        2.02GB    (264/0/0)     4241160
  7       home    wm       3 - 36092      276.46GB    (36090/0/0) 579785850
  8       boot    wu       0 -     0        7.84MB    (1/0/0)         16065
  9 alternates    wu       1 -     2       15.69MB    (2/0/0)         32130


Which looks even worse than it really is. On the disk starting at the lowest LBA I have:

  1. The boot blocks on slice 8

  2. Then alternates on slice 9 (format just gives you these for “free”)

  3. The Zpool on slice 7

  4. The second boot environment on slice 4

  5. The first boot environment on slice 0

  6. The metadbs on slice 5

  7. A dump device on slice 6


All the partitions, except the dump device are mirrored onto the other disk so both drives have the same vtoc. As you can see I can grow the zpool over both boot blocks and the metadbs when ZFS on root is completely here.


The next thing to do will be SAMBA.
