Still waiting for positive reply

Guess work here...
linux will only see the raid device as a single disc (which it really is) If you have 2 discs mirrored, really you only have 1 disc. |
yes i know i mirror only one drive will be shown
i want to ask in which file sytem i should format drives some one tell me that in NTFS is dangrous to write in linux. or should i format drives as fat 32, or linux will autometic detect and format drives in Ext3 , then how i could access my raid hdd |
filesystems
I would not prefer to NTFS, you should try ext3 or reiserFS.

Hi Mobassir Sattar khan,
Your step by step looks accurate. But NTFS isn't the best filesystem to use on a linux box. (all though it will work, but NTFS is still labled as experimental...) If you are storing data and are going to export that data to windows machines I would format the filesystem as a EXT3 or ReiserFS. If you are going to use the data on your Linux box only I still would format the disk as EXT3 or ReiserFS... ;o) Good luck Jonas |
thank you for reply
