That depends but generaly this works perfectly: md RAID1 + Grub
you have to setup GRUB to install into all your hd master boot record. This way when one fails the other can still boot the system. of course you should get in a replacement drive ASAP ;) I also have this setup with RAID5. The only thing I've not been able to put to work 100% is md+hotswap... but it works! 2007/7/17, Gabriel Lai <[EMAIL PROTECTED]>:
Thanks guys for the input. I'll test it out. Another question, if one of the hard disk failed, can the OS boot normally? Previously I tested, when I plugged out one of the hard disk, it just can't boot... I'm not sure why.... ----- Original Message ---- From: Helmut Fritz <[EMAIL PROTECTED]> To: [email protected] Sent: Tuesday, July 17, 2007 12:34:10 AM Subject: RE: [qmailtoaster] Software Raid with Qmail? i run with software raid. hehe - i did not even consider it would remove that package, but...mdadm is still on my machine after i installed with qmt-iso, and my raid is happy right now... maybe qmt-iso keeps that package in...

Well it removes sendmail and since mdadm depends on mail-client then it wipes off mdadm also. You could remove sendmail with --dodeps option or after installing qmail reinstall mdadm (since qmail provides mail-client dependency) . As far as I know mdadm is only utility for managing raid devices and software raid will function without it. I bet many of us (including me) run mailservers on software raid. Gabriel Lai wrote: Hi all, Is it okay that I configure Software Raid with Qmail? I saw in the dependency checking script that it will actually remove mdadm packages, am i right? Please advice.
