I recently helped a friend set up a 4 disc RAID-5 array, and the other day he called me and wanted to know how to verify data integrity = in case of a disc problem. Since all 4 discs are SATA I suggested he would blast data at the array (which is exported as a Samba share) and then in = the middle of that pull one of the SATA cables out. With two other computers pushing data onto the Samba share, he pulled = one of the cables. The machine detected that the disc was gone and removed it = from the configuration. gvinum then noticed the missing disc, said it was = down and then reported the plex as degraded (which is exactly what I was expecting). However, instead of then continuing to run in degraded mode, = the machine page-faulted. I do not have any details about this page-fault, = but if my friend is the only one with this problem I can quite easily get = more details by trying it again (this time with KDB/DDB compiled in and me at = the console). Has anyone else tried this? Did it work? System: * ASUS P2B-DS, 2 x 700MHz P3, 1GB ECC mem * 4 x 120GB Maxtor SATA discs hooked up to a HighPoint RocketRAID 1540 (HPT374) * 5-CURRENT (from 2004.08.02 I think, so after preemption was disabled) /Daniel Eriksson
