Hallo, habe die Frage in news.redhat.com gestellt da es scheint leider gestorben zu sein, poste ich es hier. Ich hoffe englisch ist nicht ein großes Problem, falls schon - werde ich es später übersetzen:
I am running RAID 0 on nVIDIA nForce 570-SLI with
dmraid version: 1.0.0.rc14 (2006.11.08) dmraid library version: 1.0.0.rc14 (2006.11.08)
1 2 3 | $dmraid -r /dev/sdb: nvidia, "nvidia_bafjcfea", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_bafjcfea", stripe, ok, 488397166 sectors, data@ 0 |
After successful configuration I decided to wipe my old IDE-HDD and attached it to system wrongly assuming it will be "mapped" to /dev/sdc.
Since old HDD has equal size and partition structure, stupid as I am I didnt noticed that after attaching it - mappings have changed! Old HDD became sda and two RAID HDDs became sdb and sdc respectively.
Long story short - I deleted with fdisk all partitions from sdc. And realized that I have made terrible(?) mistake only after mkfs failed to format my wiped sdc with "drive is in use" error. It was then I realized what happened.
Now, raid works as if nothing have happened and I am wondering how relevant is local partitioning information of two RAID HDDs? Or to rephraze it - is my RAID still working?
I would be grateful for any hint!
Bellow fdisk infos:
