Re: RAID5 controller
I am not sure what problems you actually had, but I think so. I heard that people are working on kernel support for proper file locking. Unfortunately we do not have the knowledge and resources to help them. We have found an acceptable indermediate solution, where main file serving is done by a Linux system and mail directories are provided by an SGI Indy.

It does sound like this could be the issue. I have no problems serving read-only file systems. On read-write file systems the Sun boxes seem to misinterpert the modes, permissions, and types of the files. -- Jean Pierre -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

The RAID functionality is implemented in hardware and appears as a normal disk to Debian. I should also mention it appears to be a normal disk to ANY OS that DPT supports. On my RAID 0 array I boot OpenDOS, NT(or should I say have booted for this one : ), OS/2, and Linux using OS/2's bootmanager. The only downside I've seen is that DPT's configuration software is not available for Linux. Not YET.

I can recommend, and we have in use the IFT 3102U (32MB) Raid Controller Infotrend Technology, Inc However I have to warn you. There is currently no support of the rpc.lockd daemon under linux.

Re: RAID5 controller
can anyone recommend a couple of tried and true RAID5 controllers i could price out? I've used the Mylex DAC960 PCI (3 and 5 channel). Very happy with them - but pricy. However, I've never used these under Linux, only SCO Unix and WinNT. However, I can't see there'd be a problem as long as Linux supports the hardware (which I'm not sure) - all RAID functions happen in hardware and are transparent to the OS.
