I cross-post a part of my ReiserFS list message, as it concernes copying of a used part of a filesystem running on top of LVM. I'd like to recover some files from a huge reiserfs file system. It is created above an LVM volume, which in its turn sits on a RAID. The LVM volume is the only one in a group which consists of the sole RAID device. I just deleted two files in a directory I know by name, the directory is still there. No writing was done after the rm, except all files copied elsewhere and diff -r'ed checked, hope that does not alter the originals. Now I'd like to play with the dd copying of the whole reiserfs (I'm avoiding the word partition since it covers the whole logical volume which spans the whole RAID device). I simply do not have space to copy the whole RAID, but the size of the used space on this reiserfs volume was under about 9 GB. I wonder how can I copy just about that -- I assume it fills the logical volume contiguously, so I can dd the first 9 GB and then try the loopback mount/rebuild. Now that I'm running it, it scrolls lines pass0: reading block 20626210 failed like crazy, perhaps up to the whole 150 GB original size declared somewhere... Then is quits, saying something about invalid argument to lseek, not surprisingly as I cut dd short. Are there LVM methods to shrink it/copy just the used blocks in conjunction with reiserfs, such as resize_reiserfs? -- Cheers, Alexy Khrabrov :: www.setup.org :: Age Quod Agis _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
