| Display all device status | metastat |
| Display device status | metastat {metadevice} |
| Display condensed status | metastat -p |
| List metadb info | metadb -i |
| Create new metadevices | metainit {volume} {number-of-stripes} {components-per-stripe} {components} |
| Attach or grow device | metattach {metadevice} {size or new device} |
| Detach device | metadetach {metadevice} {submirror} |
| Place submirror offline | metaoffline {mirror} {submirror} |
| Place submirror online | metaonline {mirror} {submirror} |
Howto: Expand a soft partition
metattach {metadevice} {size} growfs -M {mountpoint} /dev/md/rdsk/{metadevice}
Howto: Replace Failed Drive in Same Drive Slot
- Look at output for signs of failed disk slice
metastat -c
- Delete metadbs knowledge of dead drive so that we can format the new disk
metadb -i metadb -d /dev/dsk/c3t1d0s7
- Force a detach of all failed submirrors
metadetach -f d0 d20 metadetach -f d1 d10
- Remove knowledge of all failed submirrors from the database
metaclear d20 metaclear d10
- Unconfigure the failed disk, use output from first command for second command
cfgadm -al Ap_Id Type Receptacle Occupant Condition c3::dsk/c3t1d0 disk connected configured unknown cfgadm -c unconfigure c3::dsk/c3t1d0
- Replace failed disk
- Configure new disk
cfgadm -c configure c3::dsk/c3t1d0 cfgadm -al Ap_Id Type Receptacle Occupant Condition c3::dsk/c3t1d0 disk connected configured unknown
- Apply the working disk's format to the new disk and check that it worked.
prtvtoc /dev/rdsk/c3t0d0s0 | fmthard -s - /dev/rdsk/c3t1d0s0 fmthard: New volume table of contents now in place. prtvtoc /dev/rdsk/c3t1d0s0
- Add 2 copies of the metadevice database to the new disk for backup purposes
metadb -c 2 -a /dev/dsk/c3t1d0s7
- Re-create all submirrors
metainit d20 1 1 c3t1d0s0 metainit d10 1 1 c3t1d0s1
- Re-attach all submirrors to mirrors, will automatically begin resyncing
metattach d0 d20 metattach d1 d10
- Check to see percent of resync complete
metastat -c
Howto: Expand a filesystem on the fly from the global zone to the non-global zone virtual container
- Add Disk to Existing Concat/Stripe RAID 0 Volume:
root@global.zone #> metattach {metadevice} /dev/dsk/{device_name}
- Or, if using soft partitions and there is space available:
root@global.zone #> metattach {metadevice} <extra_space>
- Find out how zone filesystem is mounted:
root@global.zone #> growfs /dev/md/rdsk/{metadevice} /dev/md/dsk/{metadevice} is mounted on /zones/global.zone/root/{mountpoint}; can't growfs
- Grow existing non-global zone mounted filesystem from global zone:
root@global.zone #> growfs -M /zones/global.zone/root/{mountpoint} /dev/md/rdsk/<{metadevice}
