Ok, I'll chime in on this also.
For over 2 years I have run at least one server full-time with a 3Ware IDE
RAID controller with 4 IDE drives in a RAID level 5 configuration. I have run
this with:
Caldera OpenLinux Server 3.11
SuSE Linux Professional 8, 8.1, 8.2, 9.0, 9.1
SuSE Linux Enterprise Server 8, 9
Red Hat Enterprise Linux Advanced Server 3
Red Hat Linux 9
Red Hat Fedora Core
All without any problems. The controllers are used in a PCI-X slot and operate
in 64-bit mode. Performance is just simply great - even under extreme load
conditions. I have reported my performance metrics on this configuration at
several venues.
Please understand the following:
1. Samba has no direct involvement with hardware devices (eg: Drives)
2. Every RAID stability issue I have dealt with has been caused by
hardware and kernel driver problems
3. Software RAID in particular is an OS driver issue and NOT a Samba one
4. Samba is NOT bug free - that's a fact!
5. The Linux OS and its drivers are not bug free either
6. Bad hardware is bad hardware - this is pure and simple
7. No matter how hard anyone tries, Samba can not cure a bad hardware problem
Apart from all the above Samba still has a long way to go. Maybe, some fine
day we will all wake up to a new version of Samba that can cure coughs, colds
and global poverty. Until then, let's focus on fixing real problems and not
imagined ones. :)
