On AIX it rocks. Yes, it really surprised me. As I previously said in this thread, I wanted to try out it's case insensive behaviour. To do this I had to make a backup of the partition I was going to convert. This backup resulted in a 980MB tar.bz2 file. I then converted the 12GB filesystem with (if I remember correctly) mkfs.jfs -cO /dev/hda6. The conversion completed successfully. After mounting the directory, I did a tar xvpjf filename.tar.bz2 to the respective mount point. The last operation resulted in tar getting stuck in an unkillable D-state after extracting a random number of files from the archive. 'cp' of the archive file to the 'jfs directory' also got 'cp' stuck in D-state. After having rebooted several times, I was at last able to copy the archive file over to the directory with 'dd' and a blocksize of 4k. I hoped that extracting the file from the 'jfs directory' made any difference. It did not. bzip2 -d on the file also failed, but succeeded when I supplied -s (for small memory footprint <= 250k) It seemed like the standard blocksize for these commands did not work well with such a large file(?). I tried to extract the remaining tar file (with different blocksize), but with no luck. ...then I gave up, converted the filesystem back to reiserfs, and extracted the archive file without problems. I did not have time to investigate the issue further, and felt that I had given it a fair try. Btw: this was kernel-2.4.19-pre8-ac5. I'll probably send some more info to LKML when I have time. -p. > > []s > > -- > Rodrigo Barbosa - rodrigob at tisbrasil.com.br > TIS - Belo Horizonte, MG, Brazil > "Quis custodiet ipsos custodes?" - http://www.tisbrasil.com.br/ > Brainbench Certified -> Transcript ID #3332104 > -- Kernelnewbies: Help each other learn about the Linux kernel.
