Hi all! Once again I have problems with JFS, and once again, the fault is probably mine. This time I tried to extend a LVM volume group and remount the jfs volume with the resize option. However, I might have entered the commands in the wrong order. That is I first did a vgextend, and then resized the jfsvolume. I should have run lvextend before resizing jfs. So i did lvextend without a problem, then resized again. All seemed fine, except that the filesystem was remounted read-only. Now, I am not able to fsck the filesystem. Output from fsck is attached. Is it possible to rescue this filesystem? I am able to read the files, so I might be able to backup everything, rebuild the lvm and jfs and then move it back.
