It seems gbde has a problem when the the data written goes over the lba boundary around lba48. http://lists.freebsd.org/pipermail/freebsd-geom/2007-August/002524.html I suffered this problem error example below. Usage at the time was approx 150gig when I first noticed it. g_vfs_done():ad6s1c.bde[WRITE(offset=493964558336, length=131072)]error = 1 After reading about this problem on a few diff hits (all with no response on fixes) I tried geli. However I seen this in geli within an hour of using it. GEOM_ELI: Crypto WRITE request failed (error=1). ad6s1c.eli[WRITE(offset=0, length=131072)] couldnt really found much info on it so I have given up on freebsd encryption for now and using the disk unencrypted. No dma errors etc. all running fine. I expect the gbde is a problem and would like it to come with some warning as a modern drive is now often larger then the lba48 limit whilst I am unsure of geli as I couldnt really found much information on the problem I had so I understand its possible I had set something incorrectly although I followed the handbooks guidelines. The data itself was actually written and not corrupt but the server did crash whilst was in use occasionally so needed reboots which is no good for a production server. Chris
