Hi, I have used linux software raid1 for many years without any data loss. Now I seem to have a problem. I run a server with a pair of WD 400G drives that I keep in a raid 1 configuration. The raid became degraded but continued to function and continue to store data on the remaining drive. I simply replaced the faulty drive and rebuilt the raid. All seemed to be ok, however now I notice that 20G of data are missing from the raid. I see this by comparing to a backup device that I mirror to every night. Any idea on how can this have happened? These are the most recent 20G of data. Perhaps this is the last 20 G since the raid went bad, however that the data was clearly stored initially - I see it on the backup device I copied to. Could the data have been lost in the rebuild process? seems strange. Total of 220G of data on the device at present. The server is running debian 4.0 (etch) which runs mdadm-2.5.6-9 (debian). Linux kernel 2.6.18-5-686 Thanks Mitchell Laks -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
