Hi, I built 2.4.13 with the 2.4.11-VFS-lock.patch in the CVS. Compilation didn't give any problem as I was getting with 2.4.12-ac6. I was able to create a snapshot of a mounted LV and mount the snapshot. After this operation the I/O on the mounted LV came out with Segmentation Fault. Few months back I had reported the Segmentation fault with the I/O. That time I was getting Kernel Panic. But that time I think I had not applied the VFS Patch. Today I didn't get that kernel panic, just a Segmentation Fault. After this segmentation fault, without rebooting my system, I went ahead and started another I/O. While this I/O was going on, I created a Snapshot. But when I tried to mount it, it gave "Permission Denied". Also when I tried to unmount the LV, it came off with "File System or Volume in Use".....though It wasn't in use. Is it that I may have done something wrong, or the VFS lock patch has to be updated for 2.4.13. I am using Reiserfs File System. And everything works fine with 2.4.12. I am having problems with the later linux kernel only. regards, Aman. __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo!
