The following reply was made to PR kern/161968; it has been noted by GNATS. From: Peter Maloney <peter.maloney@brockmann-consult.de> To: bug-followup@FreeBSD.org, peter.maloney@brockmann-consult.de Cc: Subject: Re: kern/161968: [zfs] [hang] renaming snapshot with -r including a zvol snapshot causes total ZFS freeze/lockup Date: Fri, 10 Feb 2012 12:11:41 +0100 I tested this again using 8-STABLE (csup'd on 2012-01-04): FreeBSD bczfsvm1.bc.local 8.2-STABLE-20120104 FreeBSD 8.2-STABLE-20120104 #0: Mon Feb 6 12:10:32 UTC 2012 root@bczfsvm1.bc.local:/usr/obj/usr/src/sys/GENERIC amd64 on hardware: DELL PowerEdge 2850 - tested with a zfs stripe, raidz1, and raidz2 and a SuperMicro dual xeon system - tested with a zfs mirror And it didn't hang. Now there are just brief pauses every 3-5 loops (instead of hangs?). So if someone tests this in 9.0-STABLE and finds that it doesn't hang, this PR should be closed. -- -------------------------------------------- Peter Maloney Brockmann Consult Max-Planck-Str. 2 21502 Geesthacht Germany Tel: +49 4152 889 300 Fax: +49 4152 889 333 E-mail: peter.maloney@brockmann-consult.de Internet: http://www.brockmann-consult.de --------------------------------------------
