I've also tried the laptop mode tools. Somehow this seemed to spindown the disks while MD had not flushed its writes to the disks, or it did something else so I ended up with 4 disks and no array. After some crash recovery I managed to get a degraded array back with 3 out of the 4 disks. I got the 4th disk added to the array, and after some hours array was rebuild. It kinda takes the fun out of testing with live data on the disks. There's a bit over 1 Tbyte of data on the array, and backup / restoring is kinda time consuming.
@pjotr12345, I did not get my disks to spindown from commandline with hdparm -Y /dev/sd[a-d]. I did see "issueing sleep command" for all four disks, but straight after a hdparm -C /dev/sd[a-d] all disks show idle/running instead of standby. -- [Lucid] hdparm.conf change doesn't have effect https://bugs.launchpad.net/bugs/568120 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
