I need some comments in regars to my NAS. I have a Linux Server running Ubuntu 10.04 (may upgrade) and I have a RAID5 for my storage aray, it consits of 4 x 1.5 TB HDDs. OS is running on a seperate disk and I have a 1 TB USB drive that is currently empty. I am thinking of "destroying" the RAID 5, to gain additional storage space, and start using MHDDFS to mount multiple drives too one mount point for a "large array". Today I loose 1 x 1.5 TB diskspace the the RAID 5. I do not want to run 1 large volume, because if I lose 1 disk, I lose it all. Any comments in regards to using MHDDFS? I have never tried it before. Also, any comments in regards to breaking a raid5 using that is setup with MDADM. My plan is to: 1. Move 1 TB of data off the 4 TB raid 5 2. Remove 1 of the drives from the RAID5 3. Format the "broken" drive 4. Move 1.5 TB off the degraded RAID5 5. Reshape the RAID5 with 3 drives 6. Remove 1 of the drives from the "new" RAID5 7. Format the 2nd "broken" drive 8. Move 1.5 TB off the new degraded RAID5, which should be empty 9. Format the remaining 2 drives 10. Mount all drives using MHDDFS Questions: A. Is my plan viable (assumbing that I have enough data space available) B. Am I risking all the data by breaking the drives (assuming no HW failures) C. Comments in regards to MHDDFS D. Can I mount multiple drives, with data, using MHDDFS to one mountpoint? Any views and comments? BTW: I do know that I will not have any redundancy any more, but the main point is not to lose ALL data if A SINGLE drive fails. Thanks.
I am new to linux. I started with running kuki linux from a live CD on an Acer Aspire one. It worked great for what I wanted,which is an OS with minimal apps on install that I can customize as I learn more about linux and surf the web. I chose kuki because its designed specifically for the Acer Aspire one and its SSD hd, and the wifi was said to work "out of the box" (with maybe a little tweaking), which knowing a tiny bit about linux I didnt expect anything to work out of the box. When I ran it live everything worked out of the box, so I installed it. After install the wifi doesn't work. Half the time it doesn't detect any networks, when it does I cannot connect to WPA secured connection (gets stuck on authorization), sometimes I can connect unsecured for a few minutes before it looses the signal, but it usually get stuck obtaining IP address. It looks like the kernel did not update after install, so I think I'm probly missing some drivers and maybe a bunch of other stuff, I'm really new to this so I don't know what I should have or where to look to see what is there and what is not, I hope someone knows what I mean. I looked thru other forums, this seems to be a common problem for kuki and ubuntu on the acer aspire one, I tried the solutions and they didnt work, but I think those solutions assume you have a LAN connection or something which right now I dont. some of the solutions I came accross: Putting wireless drivers on a cd and then installing them, I cant figure out how, the "make" commands on the tutorial seem to not work. Someone said to reinstall WICD network manager, I can't figure out how to "reinstall". I tried making an ad hoc connection to another laptop, would not detect. I tried updating on the sketchy unsecured connection but the signal was too weak and it couldnt complete. Does it seem like my issue could be the update? how do I update the kuki kernel with no internet connection? How do I narrow down the problem so I at least know what is not causing it? Thank you in advance to anyone who helps. If there are answers for me elsewhere on the forum, I apologize for missing them and starting a new topic, please point me to them. I tried to be detailed without writing a novel, I tried linux long ago and got flamed for both, lol. In the meantime I will try and find a wired connection to borrow and see if maybe my wifi card is bad or something. Thanks again.
