Thomas Nikolajsen <[email protected]> added the comment: I tried mounting (R/W) FS from i386 kernel, like I did after applying patch, it mounts clean, without errors or redos.
Then I booted x86_64 kernel using FS as root, here I got the hammer_del_buffers error stream after some job (periodic daily) started using the FS. After that I set hw.physmem=1G as you mentioned that too much RAM could trigger problem; this seemed to help, as it didn't error out, and after rebooting normally (without limiting used memory) haven't given any errors; haven't seen any signs of problem in FS; e.g.tried mirror-read of all PFSs, as I seem to remember that you earlier has mentioned that this will check data in PFS. Enlarging UNDO/REDO buffer to 500MB seems like a good idea, if it will help making HAMMER more stable; this is 1% of 50GB, minimum recommended FS size, which doesn't seem like a high overhead. -thomas _____________________________________________________ DragonFly issue tracker <[email protected]> <http://bugs.dragonflybsd.org/issue1984> _____________________________________________________
