RAID 1 questions

Hi, I'm planning to buy a DNS-232, but I have a couple of questions on it before.

1 -  If I have both hard drives mounted in RAID 1 fashion, up and running, can I shut down the NAS, remove one of the drives, install it on an empty USB hard drive rack, and access its data with windows XP / Vista right away (With ext2ifs installed, for sure) without any problem ?

2 - Basicly, I would like to cycle within 3 hard drives. I want two of them in RAID 1 mode. Once a while, I'ld like to remove one on the hard drives, and secure it in a fire safe or somewhere else, as a backup. Then, take the third one, and install it in the NAS, get it synced, and get a RAID 1 setup once again. (Not sure if I have to format to new drive everytime ?, if there's old data on it from the previous mirrored setup)

3 - Do you know if the NAS support french caracters, like (é, è, ê, ç, à, ï, ë) ? For unknown reason, I have an NSLU2 that screwed up a lot of my mp3's filename. These french caracters were replaced by some strange symbol I've never seen before. It ended up in a big mess.

Thanks a lot !

Re: RAID 1 questions

1 - Yes

2 - That is NOT what RAID1 is meant for, and if you try that you are going to have difficulties - there are other ways to achieve what you want, but RAID1 is not the way.

3 - The DNS-323 with fw 1.04 and later supports unicode and should support french characters, although I've never personally tried it.

Re: RAID 1 questions

2 - What is RAID 1 meant for then ? The thing is that I'ld like to get a secured backup not installed in the NAS system, and update this one once a while (In case of a fire, flood or so). And at the same time, running two mirror in the NAS, to be able to access my data if one of the drives fail.

That'll then be double protection : backup on an inactive drive (in case of fire, virus, etc. ) and redundancy if case of drive failure (the remaining drive in the NAS will be more updated that the one in the fire safe.)

What do you think ?

4 - And also, what file system are supported in the latest software ? I know EXT2. But what's about EXT3, NTFS and FAT.

Re: RAID 1 questions

2 - RAID 1 is meant for redundency.  This means if 1 drive fails, the data is still available to the end user who does not even know a failure occured.  (Example of an environment where the end user is not the administrator.)  Consider putting one of your drives into a USB case and connecting that to the DNS.  You can user rsnc to back-up the mirror to the USB drive, then you can stor away the USB drive anywhere you want.

4- EXT2 is the only one supported.  EXT3 has been run unofficially by a few people with good results.  I have used NTFS, but the NTFS had disaterous results, so I use EXT2.

Can you see my signature?  What does it say?

Now - would you like to guess why it's in my signature?
