https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D189174 Robert Schulze <rs@bytecamp.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rs@bytecamp.net --- Comment #6 from Robert Schulze <rs@bytecamp.net> --- This patch breaks sparse file creation entirely. I'm running 10.3-p6 and creating a sparse image for md-usage with dd is not possible, md cannot attach it. A sparse file created with truncate works. I've reverted to r266488 and it works again. Here is the output on non-reverted 10.3: # dd if=3D/dev/zero of=3Ddisk bs=3D1M count=3D512 conv=3Dsparse 512+0 records in 512+0 records out 536870912 bytes transferred in 0.255875 secs (2098175593 bytes/sec) # ls -lsh 0 -rw-r--r-- 1 root wheel 0B Aug 30 14:29 disk After reverting I got this: # dd if=3D/dev/zero of=3Ddisk bs=3D1M count=3D512 conv=3Dsparse 512+0 records in 512+0 records out 536870912 bytes transferred in 0.458561 secs (1170773306 bytes/sec) # ls -lsh 96 -rw-r--r-- 1 root wheel 512M Aug 30 14:27 disk --=20 You are receiving this mail because: You are the assignee for the bug.=
