https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D228359 --- Comment #24 from freebsd@ihead.ru --- Created attachment 193838 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D193838&action= =3Dedit fsck_ffs -E -d /dev/mirror/gm0 on fs with 390gb data after gmirror rebuild This test was done on following way: FS (mounted on /mnt) contained 200G of data. gmirror remove gm0 ada1 gmirror insert gm0 ada1 dd if=3D/dev/zero of=3D/mnt/1.tst bs=3D10m count=3D102400 On another terminal i run systat -vmstat. After few minutes ada1 become 99% busy (ada0 was busy at 33%), MB/s lowered from 255 Mb/s (sata2 controller used on this machine) to 85 MB/s. dd was stopped when file /mnt/1.tst reached 190G size. And finally umount /mnt fsck_ffs -E -d /dev/mirror/gm0 I could not reproduce the problem when fsck_ufs run more than 6 minutes. --=20 You are receiving this mail because: You are the assignee for the bug.=
