Software Raid & OS Reinstall

WingnutOne · 01-17-2008, 06:02 PM

Given the following:
Fedora 8 OS is installed on drive sda and a software RAID5 was built on sdb, sdc, & sde.

If the sda drive dies and has to be replaced - which necessitates reinstalling the OS - would the reinstalled OS be able to recognize the existing software RAID5 on drives sdb/c/d?

I'm not sure exactly how software RAIDs work. Is all the information for their definition and set-up stored on the physical drives included in the RAID, or is the RAID defined only within the OS that created it?

Thanks,

SW RAID is not very much dependent on the OS hence even you replace the disk it will not make much difference. At a max you might need to re-generate the mdadm.conf file.
