Operating Systems Solaris forgot metaroot command Post 84919 by pressy on Thursday 29th of September 2005 12:21:31 PM

well mate, the system will load the kernel, but when the ufs-boot will forceload the metadrivers from the /etc/system for the kernel initialization there will be an entry like:
rootdev:/pseudo/md@0:0,0,blk
so the kernel tries to load the next modules from a device which doesn't exist. panic --> next try --> panic --> next try --> Smilie

i would do the same, boot from CD, change the md entries in the vfstab back and delete the sds-forceloads and rootdev from the system file
Code:
forceload: misc/md_trans
forceload: misc/md_raid
forceload: misc/md_hotspares
forceload: misc/md_sp
forceload: misc/md_stripe
forceload: misc/md_mirror
forceload: drv/pcipsy
forceload: drv/simba
forceload: drv/glm
rootdev:/pseudo/md@0:0,0,blk

by the way, just for info: a sds database default length is 8192 blocks, that would be around 4 MB on a 512b LBA disk (-l would be the option from metadb to change that if your LBA is smaller) . i would recommend to make at least 3 copies/disk to prevent block errors, so we are on 12MB. usually i make 256MB slices, so i am prepared for VxVM aswell. the recommendation from sun for slice 7 is based on a suncluster enviroment, there the metadb's must be on slice 7 on the internal disks, and if you add a external disk to a metaset the db is automaticaly created on slice 7.

greetings PRESSY
