> I thought RAIDZ would correct data errors automatically with the parity data. Right. However, if the data is corrupted while in memory (e.g. on a PC with non-parity memory), there's nothing ZFS can do to detect that. I mean, not even theoretically. The best we could do would be to narrow the w

Thanks for your reassuring post, loomy :) I'm pretty sure the reason for all this is some bad hardware.. But I can't get VTS to work, looks like its not supported for this kind of hardware. And in order to run some other stresstest software or something I would have to connect monitor, keyboard

haha very funny :D Just the controllers are on a 32bit PCI bus.. solaris itself is running 64bit: [EMAIL PROTECTED] /var/tmp/ # isainfo amd64 i386 And besides, a lot of our customers are having serious problems with their thumpers and zfs and stuff... This message posted from opensolaris.

Hey Thanks for your answers guys. I'll run VTS to stresstest cpu and memory. And I just checked the block diagram of my motherboard (Gigabyte M61P-S3). It doesn't even have 64bit pci slots.. just standard old 33mhz 32bit pci .. and a couple of newer pci-e. But my two controllers are both the sa

My guess is that you have some defective hardware in the system that's causing bit flips in the checksum or the data payload. I'd suggest running some sort of system diagnostics for a few hours to see if you can locate the bad piece of hardware. My suspicion would be your memory or CPU, but tha

hi folks I've been running my fileserver at home with linux for a couple of years and last week I finally reinstalled it with solaris 10 u4. I borrowed a bunch of disks from a friend, copied over all the files, reinstalled my fileserver and copied the data back. Everything went fine, but after
