https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254530 --- Comment #2 from Patrik Hildingsson <patrik@hildingsson.se> --- (In reply to Alan Somers from comment #1) 1) Please see the below copy/paste from a 13.0-RC3 system where it seems to work just fine. root@testbsd:~ # sysctl -w vfs.zfs.vol.mode=2 root@testbsd:~ # zfs create zroot/test root@testbsd:~ # zfs create -o volmode=dev -V 50M zroot/test/disk0 root@testbsd:~ # dd if=/dev/random of=/dev/zvol/zroot/test/disk0 dd: /dev/zvol/zroot/test/disk0: end of device 102401+0 records in 102400+0 records out 52428800 bytes transferred in 1.016171 secs (51594487 bytes/sec) root@testbsd:~ # zfs snapshot zroot/test/disk0@test-now_ok root@testbsd:~ # dd if=/dev/random of=/dev/zvol/zroot/test/disk0 dd: /dev/zvol/zroot/test/disk0: end of device 102401+0 records in 102400+0 records out 52428800 bytes transferred in 0.833823 secs (62877584 bytes/sec) root@testbsd:~ # zfs snapshot zroot/test/disk0@test-now_ok-2 root@testbsd:~ # dd if=/dev/random of=/dev/zvol/zroot/test/disk0 dd: /dev/zvol/zroot/test/disk0: end of device 102401+0 records in 102400+0 records out 52428800 bytes transferred in 0.444901 secs (117843859 bytes/sec) root@testbsd:~ # zfs create -V 52428800 -o 'reservation=none' -o 'volblocksize=8192' -o 'checksum=on' -o 'compression=lz4' -o 'readonly=off' -o 'copies=1' -o 'logbias=throughput' -o 'dedup=off' -o 'sync=standard' -o 'volmode=dev' -o 'snapshot_limit=none' -o 'redundant_metadata=most' zroot/test/disk1 root@testbsd:~ # zfs send zroot/test/disk0@test-now_ok | zfs receive -F zroot/test/disk1 root@testbsd:~ # uname -K 1300139 root@testbsd:~ # uname -U 1300139 2) No, I did not try 12-STABLE. I have only tried 12.2-RELEASE-p4. I have reproduced the error on two different installations of 12.2-RELEASE-p4. 3) The paste indeed looks suspicious. I forgot to trim away the prepending "root@lrrr:~ ", other than that it is correct. I did not leave out a trailing forward slash. It isn't supposed to be there. ZFS incorrectly prompts that there is a trailing forward slash. -- You are receiving this mail because: You are the assignee for the bug.help
