Hello all
I am having a problem with errors when copying data via samba to my FreeBSD 7.1 box running zfs raidz.
ad4: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=92289078
ad4: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=184601263
ad4: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=96519130
ad4: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=99903315
ad4: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=99903317
Now Initially I was getting these errors more frequently as well as random hard disks vanishing from the system. My initial thought was the PSU was at fault eg it was old and not hugely powerful.
ad4: 238475MB <Hitachi HDP725025GLA380 GM2OA52A> at ata2-master SATA150
Now I have replaced this disk with brand new Hitachi of the same make and model today and the problem still seems to be there all be it much less frequent.... and as just as I am writing this the machine crashed with a panic ad6 disconnected.
Any advice would be greatly welcomed
