I had seen this same problem in a prior version and had emailed the following comment to the list with no reply: ... With linux 2.0.36 and patch raid0145-19990421-2.0.36 applied, if a disk is looked at for autostart but rejected because it's superblock is out of date, you can't raidhotadd or raid

Best Setup?

1999-07-22 Thread Bryan Batchelder
Hi everyone-- I have been on this list for a little while now, and I am wondering what the concensus is on what is the most robust/stable setup for RAID under RedHat 6.0/Kernel 2.2.5 (or a later kernel if it means better performance/stability). I am getting ready to set up a serv

1999-07-22 Thread Egon Eckert
On 2.0.37+raid990713 (recent), when I stop my raid1 device (using raidstop), it refuses to 'raidstart' (I have to reboot to get /dev/md0 active again). Is it a bug or a feature? :) Here it is: -- ego2:~# cat /proc/mdstat Personalities : [raid1] [raid5] read_ahead 1024 sectors md0 : activ

I could be off my rocker, but I believe the answer your looking for is the fact that Lilo cannot correctly use a raid for booting. Typically I would imagine you would settup / as the mirror, and perhaps make a /boot that's it's own non-raid partition for kernel images and such, thusly lilo would
