A bit of background
I'm running a Nexenta (OpenSolaris kernel + a number of Debian tools) server running a ZRAID of 3x 1TB SATA2 drives (essentially a RAID5 formatted in ZFS, for those who aren't familiar with zpools).
When running the ZFS scrub command (ZFS's equivelent of fsck) I get a number of checksum errors. As I'm almost certain the drives are healthy and these errors have only started popping up when I installed some new RAM, I'm pretty sure the errors are RAM related.
So my question is this:
Is there any UNIX/Linux tools that can scan the RAM for damaged blocks and then badlist them - thus preventing future memory checksums?
the server has 6GB RAM (3x 2GB DDR2 sticks), so there's more than enough RAM even with badlisting whole chunks - thus I don't want to pay for new chips unless i really have to.
Also, if said command can run in real time or on a live system, then that will be a bonus (though I understand that the obvious dangers of doing so might make such an opinion impossible/impractical)
