Problem Statement Top
On a system running Solstice DiskSuite[TM], all mirrors show a state of "Needs maintenance" after rebooting the system. This occurs on all mirrors on the system, including the root disk, if that, too, is under DiskSuite control.
The mirrors are able to be turned into an "Okay" state by using the metaclear and metainit commands. However, when the system is rebooted, the mirrors return to a state of "Needs maintenance."
An example of this condition is seen by the metastat command:
# metastat
d0: Mirror
Submirror 0: d10
State: Needs maintenance
Submirror 1: d20
State: Needs maintenance
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)

Resolution Top
This may be caused by the "metasync -r" command not getting executed when the system boots, or if the system boots up only to single-user mode.
This metasync command is normally executed in one of the startup scripts run at boot time.
For Online: DiskSuite[TM] 1.0, the metasync command is located in the /etc/rc.local script. This entry is placed in that file by the metarc command.
For Solstice DiskSuite versions between 3.x and 4.2, inclusive, the metasync command is located in the /etc/rc2.d/S95SUNWmd.sync file.
For Solstice DiskSuite version 4.2.1 and above, the metasync command is located in the file /etc/rc2.d/S95lvm.sync.
In all cases, because this script is not run until the system transitions into run state 3 (multi-user mode), it is to be expected to have both submirrors in a "Needs maintenance" state until the command is run. I/O to these metadevices works just fine while in this state, so there is no need to worry. |
