Hi,
Apologies guys, I know this is the wrong list, but am unsure which list to use. Data integrity can be considered a security topic :-)
hdb: dma_init: status=0x51 {DriveReady SeekComplete Error} hdb: dma_init: error=0x84 {DriveStatusError BadCRC}
DMA error.
ide: failed opcode was : unknown
Controller fails. If a disk has erratic blocks, it will loose first DMA, then tries PIO, and at last reset the bus. I had to recover failing harddisk several times for customers, this one looks a bit different, as I always had IDE opcodes and reset messages in log. The freezing system is a sign for kernel trouble. Samba and LVM should not cause the trouble - my first guess would be failing disks, second guess failing controller (in most cases chipset on mainboard), third a bad IDE driver / kernel combination. Backup your Data first. Try to use a vanilla kernel. If the error stays, exchange mainboard or use an external controller (i.e. a Promise card). Use fsck. If you still have errors the disks are broken. Ciao, Dieter
