https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199804 --- Comment #3 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Toomas Soome from comment #2) I think this fix is not completely correct. Now you use the data block size as the hole size. I think that the hole size should be determined based on the level of the hole. Essentially, if the hole is at the zero level, then it covers dn_datablkszsec * 512 bytes of data (one data block). If the hole is one level above, then it covers as many data blocks as a number of block pointers that fit into one indirect block. And so on. Please note that (nlevels - i - 1) is the level number in the loop. E.g. search for BP_SPAN() that is used elsewhere for the same purpose. -- You are receiving this mail because: You are the assignee for the bug.
