joys of joys today. One success in one place, a failure else where! basically one of my HDD's in my ubuntu based NAS has gone awful funny. This seems to be effecting large files only at the moment, how big i cant say but it failed on a file of about 800mb. I can copy data of 6GB of more if anything there isn't a limit on that, onto the drive, however trying to copy it from there to anywhere else it simple fails with an I/O error, fail to read file. I am stumpt! So err in typical forum thread, as the saying goes HELP!!!
http://www.ubuntu.com/getubuntu/rel...orruption of large files with ext4 filesystem Yes? No? I don't know. I don't use Ubuntu (I use its daddy ). But it could be related if not necessarily the cause.
yep thats the one ext4 in use. so im screwed right! I spent so long on 9.04 and was happy, but the upgrade to 9.10 was so easy, why not i asked. regret and pain now!
right after several hours of googling trying to find a solution to recovery i found ddrescue, this is where it gets odd. i required the names of my drives for ddrescue, so i opened up Gparted. Gparted has a repair feature! Right now i can copy stuff off, too which i am doing, however the used space went from 115Gb to 89Gb, so something has been lost. oh well, at least its progress!
Wouldn't happen to be a Samsung F3 1TB this HDD would it? I've had one go on me in one of my systems after it chucked out read, write and CRC errors for weeks causing all kinds of havoc.
na it was an old 250Gb hitachi, solid drive, but the ext4 filesystem on it has a bug, pointed out above. That bug is exactly my problem. Managed to fix the filesystem enough to copy my stuff off it, and revert it to ext3 for safety reasons. Oddly at the time i went ext4 because the wiki explained its better at organising large files. Sod that!
