>Hi Linux fans, > >My English is not my first language, I hope the story below is understandable. > >I have a xbuntu machine with 2 hard drives, one for the system, one that >is for backups. The drive for backups is an old, noisy hard drive, so therefore >i would like it to spin as little as possible. > >In the current configuration, I don't mount the backup drive, and put it >to sleep with HDparm -Y late in the boot process. When it's time to create >the backup, I mount the backup drive, perform the backup, unmount the drive, >and put the drive back to sleep. This works fine, the backup disk only spins >when the backup is being made. > >Now i want to mount the backup drive read-only, so the users can bring back >deleted files themselves. When i mount my reiser disk read-only, and put >it to sleep, the drive wakes up.
