Re: Soft RAID-5 + LVM file system corruption

Some updated, to close that issue for those who will find it in the list later.

File system corruption was not the only anomaly in my system, for example WiFi card had different MAC address every boot and few more interesting things...

I've replaced memory modules although memtest didn't find any problem with all its tests. It's too early to be sure, but so far everything looks fine, so I'm staying with LVM over RAID5 for now since its the most flexible way to manage hard disk space.

Hello all,

A system question, not so VDR related, but I hope someone in the list use the same configuration.

From time to time my system won't boot since ext3 file system got corrupted and asks me to log in as root and run fsck manually. No bad blocks are found, just incorrectly stored nodes that are always fixed.

I have 3 320GByte SATA disks partitioned to several large partitions, those partitions are configured to software RAID-5 between disks and on those RAID-5 partitions there are 2 LVM volumes, one for system and another for storage.
There are also 250 MByte partition on every disk, while 2 of them are configured to software RAID-1 and mapped to /boot.

System LVM gets corrupted more often since its used more intensively.

Does anybody here have the same configuration? Or any other software RAID-5 configuration?
Did anyone faced such problems? Maybe someone facing the same problem without RAIDs?
Any help will be appreciated.

I'm running on Fedora 10 with 2.6.27 kernel.
I had the same problem with Fedora 8 as well.

Thanks.
Alex.
