https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251578 Bug ID: 251578 Summary: sysutils/zfstools warnings with ZVOLs Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: bdrewery@FreeBSD.org Reporter: ml@netfence.it Flags: maintainer-feedback?(bdrewery@FreeBSD.org) Assignee: bdrewery@FreeBSD.org I'm testing sysutils/zfstools, which will create hourly snapshots of all my= ZFS pools, on a 12.2 box. However, I see in the logs, every hour, the following messages: > kernel: g_dev_taste: make_dev_p() failed (gp->name=3Dzvol/zroot/vm/win10t= est/disk0@zfs-auto-snap_hourly-2020-11-28-16h00, error=3D63) > kernel: g_dev_taste: make_dev_p() failed (gp->name=3Dzvol/zroot/vm/win10t= est/disk0@zfs-auto-snap_hourly-2020-11-28-16h00p1, error=3D63) > kernel: g_dev_taste: make_dev_p() failed (gp->name=3Dzvol/zroot/vm/win10t= est/disk0@zfs-auto-snap_hourly-2020-11-28-16h00p2, error=3D63) > kernel: g_dev_taste: make_dev_p() failed (gp->name=3Dzvol/zroot/vm/win10t= est/disk0@zfs-auto-snap_hourly-2020-11-28-16h00p3, error=3D63) > kernel: g_dev_taste: make_dev_p() failed (gp->name=3Dzvol/zroot/vm/win10t= est/disk0@zfs-auto-snap_hourly-2020-11-28-16h00p4, error=3D63) Now: _ win10test is a zvol: I'm not really interested in it and I could disable snapshots on it (or even delete it), but I want to understand things; _ looking for this in forums, I see someone suggesting error 63 means the snapshot name is too long; that's strange, as I've got even longer names (n= ot zvol, though); _ anyway, if it's true, I guess snapshot should not be created, but they are there; they also get deleted the next hour, since this volume is not in use= , so there's really no change; _ I tried this on a different machine (still at 12.1) and I get a different message: > kernel: ZFS WARNING: Unable to create ZVOL zroot/vm/win10test/disk0@zfs-a= uto-snap_hourly-2020-11-28-16h00 (error=3D63). Still the snapshots are there. _ I guess ...p1, ...p2, ...p3, ...p4 refers to the partitions on the volume= (in fact listed in /dev/zvol/zroot/vm/win10test/); I guess this should not be attempted at all; _ I've seen https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D215067 and = it's quite scary. Do we have to pay attention not too create too long names? --=20 You are receiving this mail because: You are the assignee for the bug.=
