.../BDOS, where "directory" and block mapping are essentially synonymous. And now I understand about the timing. Makes sense when you describe it that way. My system is ext4, although I doubt that I used "flex_bg" option, since this was first created awhile back. I did try to run e4defrag. It simply said that no defrag was needed. So, now I'm only left in need of a work-around. Perhaps a way to have the system load the bitmaps at boot time in the background? It would need to be done in such a way that it would not block any other access to that system. Or, is there a better fi...

I asked about this a while back. It seems that this problem is getting much worse. The problem/issue: there is a very long delay when my system does a write to the filesystem. The delay now is over 5 minutes (yes: minutes). This only happens on the first write after booting up the system, and only for large files - 1GB or more. This can be a serious problem since all access to any hard disk is

...ugfs. The badblocks program now correctly recovers from I/O errors when direct I/O is being used. The badblocks command now also supports a -B option which forces the use of buffered I/O, and the -v option will provide a more detailed breakdown of read, write, and failed comparison errors. Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl. Added support for journals larger than 2GB. Support using both hard links and symlinks when installing e2fsprogs. Add overflow checking to tune2fs -i's fsck interval, which must fit in a 32-bit field. The debugfs command now has a new 'blocks...
