Another power problem

    My NAS200 has been running fine for about 3 months after upgrading to the Jac0 firmware and cleaning up the problems I had. But I appear to have had another power surge / spike and now I'm stuck.

    The NAS200 is flashing the power and full lights alternately (it ends up this way after powering up). The reset button doesn't seem to work for either the short or long reset - no beeps. I can't access the web, or via SSH which worked before.

    I have no idea what I can do to get out of this, so I'm hoping the forum has some ideas.

    I decided to remove the disks, which allowed the NAS200 to start up. Then I installed the V34R75 firmware. As promised, it started up without requiring the scandisk. So now I'm back in business.

    I've moved the second disk drive to another system in an enclosure to allow a separate backup from the NAS200.

    Would anyone care to share opinions about the merits of switching to the non-journaled file system for performance? If I have a separate backup this approach seems safe - am I right?

    The Jac0 firmware is based on R62 which has a problem that it lets everything wait for a filesystem fix at boot-up. The new R75 (alledgedly) fixes this.

    Hopefully Linksys releases the source code for R75 soon so I can put an update of my firmware online.

    I've had ext2 on my second harddisk almost since the beginning, after I installed R71 Beta for a short time. The performance difference is very noticeable (6MB/s vs 4MB/s) which makes it worthwhile all by itself.

    Another advantage of using ext2 is that ext2 is more widely supported by other operating systems than XFS. There's even a program (the name escapes me at the moment) to access ext2 filesystems under Windows. That makes it possible to access the data on the disks in case your NAS dies.

    Having a backup of the data that's on your NAS is always a good idea and I highly recommend it. A backup on a separate system (as opposed to backups from one NAS200 disk to the other) makes sense because that way the NAS200 hardware won't be a potential Single Point of Failure. The backup will be slow if you have to backup one network device to another, so the higher intrinsic performance of ext2 also makes sense, but this shouldn't really be a reason to switch to ext2.

    Would that be ltools?

    I hope that the GPL version is released soon so you can do your magic again. I still have disk 1 formatted as XFS, and will keep it that way until I can complete a backup. The first backup is going to take a while since the NAS performance seems to have slowed down since I ran benchmarks last August - I used IOzone to check - so I'm hoping to be able to run a defrag tool before long.

    Hooray! Linksys released source code for R75 firmware!!!
    Jac, are you planed to update NASi200 project to latest release?
