Hello, I have a c5 box with a 6 drive raid 6 array. I was going away over Christmas so I was shutting the machine down, I noticed a raid resync (on the raid 6 array) so i stopped it, using the command # echo "idle" > /sys/block/md5/md/sync_action then shut the machine down. A week later I turned the machine on and started copying data to it around 24 hours later a raid resync occurred and wiped all the new data I had copied to it. To me this seems broken, is it because I manually stopped a previous resync that it got in this state? Any ideas? As for log messages there is nothing in the /var/log/messages file, only Jan 2 19:38:39 bolivia kernel: md: syncing RAID array md5 Jan 2 19:38:39 bolivia kernel: md: minimum _guaranteed_ reconstruction speed: 1000 KB/sec/disc. Jan 2 19:38:39 bolivia kernel: md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for reconstruction. no other errors or anything. Thanks Nathan
