Hello. I have a stock RHat 6.0 upgraded to 2.2.13 and the raid works fine. However during the reboot the /dev/mdX partitions can't be fsck'd as raidstart fails to start up. How do I configure my init.d scripts to invoke raidstart as appropriate? STeve

Problems with linear RAID

1999-12-06 Thread Patrik Rådman
Hi, I'm trying to create a linear RAID of two loopback devices. The code in the standard 2.2.13 kernel acted very strangely, (sometimes it worked, mostly it didn't) so I downloaded the raid0145-19990824-2.2.11 patch, and raidtools of the same date. However, I can't create /dev/md0 with the new r

fsck vs. RAID-1

1999-12-06 Thread Stephen Walton
Short and simple version of my previous long winded message: I can't auto-mount my RAID-1 on bootup, because the rounding done by mkraid means that the file system size doesn't agree with the partition size, which causes the bootup fsck to fail with an error. Is there a fix or workaround? RedHa

A few notes: 1) We have been using Linux NFS here for years. Once you have it running it appears to be rock-solid. We've even NFS mounted a filesystem, from another server, and then shared it out over Samba, to client workstations. This was a production configuration and it lasted for years, until

Just to verify - you would like to create a Raid5 on 1 machine and share it via NFS, or would you like to create a Raid5 out of other machines' drives shared via NFS? (the first is very reliable, but the latter is a little far fetched, though may be technically possible) My impressions of Raid a
