Hi folks,

after a while running ok I have got the following tomorrow:

> ad6: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=475111936
> ad6: FAILURE - WRITE_DMA48 status=51<READY,DSC,ERROR> error=10<NID_NOT_FOUND> LBA=475111936

> g_vfs_done():gvinum/data[WRITE(offset=486514360320, length=131072)]error = 6
> g_vfs_done():gvinum/data[WRITE(offset=486514753536, length=131072)]error = 6
> g_vfs_done():gvinum/data[WRITE(offset=486514884608, length=131072)]error = 6

ad6 is connected to the onboard VIA 6420 SATA150 controller, it is
data.p0.s2.

The machine rebooted itself some time after this messages it seems.
I did a gvinum start data.p0, now the RAID is up again, but the fsck I
did afterwards printed many unexpected inconsistencies :( And over 700
files are in lost+found.

smartmontools tell me the disk is ok so far, any idea what happend here
or what I can do that this doesn't happen again?

I'm currently updating to the newest 6-STABLE...

regards
Marius
