missing partition labels ?

[Mike Tancsa]

For some reason, when I moved my disks to a new chassis, the partition 
lables disappeared from my disks.  The server boots up fine, as it is a 
mirrored zfs system.

zpool status shows

   pool: zroot
  state: ONLINE
   scan: none requested
config:

         NAME                               STATE     READ WRITE CKSUM
         zroot                              ONLINE       0     0     0
           mirror-0                         ONLINE       0     0     0
             diskid/DISK-WD-WCC3F4085561p3  ONLINE       0     0     0
             diskid/DISK-WD-WCC3F4063296p3  ONLINE       0     0     0

errors: No known data errors

which is correct.

However, I no longer see the partition lables associated with /dev/adap#

It used to look like
# ls -l /dev/ada*
crw-r-----  1 root  operator  - 0x64 Aug  8 17:32 /dev/ada0
crw-r-----  1 root  operator  - 0x67 Aug  8 17:32 /dev/ada0p1
crw-r-----  1 root  operator  - 0x69 Aug  8 17:32 /dev/ada0p2
crw-r-----  1 root  operator  - 0x6b Aug  8 17:32 /dev/ada0p3
crw-r-----  1 root  operator  - 0x6d Aug 11 12:45 /dev/ada0p4
crw-r-----  1 root  operator  - 0x6f Aug  8 17:32 /dev/ada1
crw-r-----  1 root  operator  - 0x76 Aug  8 17:32 /dev/ada1p1
crw-r-----  1 root  operator  - 0x78 Aug  8 17:32 /dev/ada1p2
crw-r-----  1 root  operator  - 0x7a Aug  8 17:32 /dev/ada1p3
crw-r-----  1 root  operator  - 0x7c Aug 11 12:45 /dev/ada1p4

now it looks like

# ls -l /dev/ada*
crw-r-----  1 root  operator  - 0x5b Aug 11 14:18 /dev/ada0
crw-r-----  1 root  operator  - 0x5f Aug 11 14:18 /dev/ada1
crw-r-----  1 root  operator  - 0x67 Aug 11 14:18 /dev/ada2
crw-r-----  1 root  operator  - 0x73 Aug 11 14:18 /dev/ada3

The problem is, I cant get HAST to use the diskid so my replication is 
broken now.


# ls -l diskid/
total 1
dr-xr-xr-x  2 root  wheel     -  512 Aug 11 14:18 .
dr-xr-xr-x  9 root  wheel     -  512 Aug 11 14:18 ..
crw-r-----  1 root  operator  - 0x5e Aug 11 14:18 DISK-S1ANNSAF225153X
crw-r-----  1 root  operator  - 0x69 Aug 11 14:18 DISK-S1ANNSAF225154J

crw-r-----  1 root  operator  - 0x88 Aug 11 14:18 DISK-WD-WCC3F4063296p3
crw-r-----  1 root  operator  - 0x89 Aug 11 14:18 DISK-WD-WCC3F4063296p4
crw-r-----  1 root  operator  - 0x6a Aug 11 14:18 DISK-WD-WCC3F4085561
crw-r-----  1 root  operator  - 0x75 Aug 11 14:18 DISK-WD-WCC3F4085561p1
crw-r-----  1 root  operator  - 0x76 Aug 11 14:18 DISK-WD-WCC3F4085561p2
crw-r-----  1 root  operator  - 0x77 Aug 11 14:18 DISK-WD-WCC3F4085561p3
crw-r-----  1 root  operator  - 0x78 Aug 11 14:18 DISK-WD-WCC3F4085561p4

It errors out with

  [disk1] (secondary) Unable to open diskid/DISK-WD-WCC3F4085561p4: No 
such file or directory.

Somehow the geom name got changed ?
