Wolfgang, thank you very, very much for your advice. As you told me, I've downloaded "fresh" copies of Linux 2.4.21 kernel, LVM 1.0.7 and linux-2.4.21-VFS-lock.patch (at http://evms.sourceforge.net/patches/1.2.1/2.4.21/). Following your instructions, I generated and patched the kernel using lvm-1.0.7-2.4.21.patch. After that, I tried to patch the kernel using linux-2.4.21-VFS-lock.patch and I received an error message from patch program requiring me a file path to patch evms.c source file. I do not have installed evms package, so I decided to skip that patch, and continue patching lvm module and I recompiled the whole kernel using my custom configuration (make menuconfig; Load configuration option...). Now, I'm able to create a snapshot and mount it, but I receive a strange warning message (even if I mount it readonly): $~# mount -t ext3 -r /dev/storage/snap /mnt/temporal/ Can't write to read-only device 3a:04 kjournald starting. Commit interval 5 seconds Can't write to read-only device 3a:04 EXT3-fs: mounted filesystem with ordered data mode. Anyway, the snapshot is mounted and it's visible... So, it seems to work... What's your opinion about this? Thanks a lot for you help and advice, Alberto Picon -- Alberto Picon Couselo Depto.
