Then you should trespass line 1389 in BlockAllocator.cpp, ie. the checking process is trying to delete a file - can you confirm? If that's not the case, we need a generic mechanism that defers trimming when the check is run.

Just don't format that partition for now ;-)

If you mean

   1389 					inode->Node().flags

this, then no, it isn't hit.

Attaching my KDL. Seems the same bug. hrev28752 on real hardware (IBM R52). My /boot is a 20Gb partition on the main hard disk. I've been using it for 2 weeks without any problem, except a few KDL. To update my system, I always update a 200Mb image on an USB key, then boot from USB key, and diff -r the key and the disk beos/ dirs, then copy the file which differ.

Yesterday the diff/cp process went fine but at reboot, the bootloader said 'Current Boot volume: (None)'. I rebooted on the USB key, rediffed -r and it reported that kernel_x86 was different, although I had copied the newer one. I copied it once more from the key, rebooted, and all went fine.

Today, the same problem appeared, despite the fact that after diff/cp operations, I runned "sync;sync;sync", unmounted the hard drive partition, then remounted it. You bet it, mounting and rediffing showed differences on some files I had copied before unmounting...

I decided to checkfs my hard drive volume, and it leds me to the attached KDL.

Note that I'm not very familiar with KDL and kernel internals. I read the tutorial on, but didn't understand everything. If you need me to investigate, I suggest you guide me with commands to type...

Sorry, Trac refuses to post my attachment, complaning "failed to create unique name" 3 times and one time crashing completely because of "too many open files". I strongly believe this problem comes from the hosting machine.

It's a known problem that happens to Trac every now and then, nielx has been working on trying to find what causes it.

Resolution: fixed
Status: newclosed

Should be fixed in hrev28845, please confirm.

Fixed for me. I have been able to check my main FS on the Thinkpad without problem from an up-to-date Haiku (hrev28845) on an USB Key. BTW, no errors were reported by checkfs.

Thanks and have a happy new year !
