Hi, Following setup: Two identical fileservers connected directly via their em1 interfaces. Both running RELENG_6 from early October. fs2 exports a 924GB volume via ggated which is imported by fs1. fs1 spans a gmirror across its da1s2d and this ggate0 (->fs2) device. It was just rebuilding the gmirror, when I figured, I'd try to backup all (rather empty) volumes to tape. So dump(8) was running on the gmirrored filesystem and was in the process of snapshotting the device. It did spit out several of these lines 2006-10-24T15:25:34+0200 <kern.crit> fs1 kernel: GEOM_MIRROR: Request failed (error=5). ggate0[WRITE(offset=1017607733248, length=16384)] 2006-10-24T15:25:34+0200 <kern.crit> fs1 kernel: g_vfs_done():mirror/share[WRITE(offset=1017607733248, length=16384)]error = 5 2006-10-24T15:25:34+0200 <kern.crit> fs1 kernel: g_vfs_done():mirror/share[WRITE(offset=1017800425472, length=16384)]error = 5 2006-10-24T15:25:34+0200 <kern.crit> fs1 kernel: g_vfs_done():mirror/share[WRITE(offset=1017993117696, length=16384)]error = 5 2006-10-24T15:25:34+0200 <kern.crit> fs1 kernel: g_vfs_done():mirror/share[WRITE(offset=1018185809920, length=16384)]error = 5 and paniced several seconds later: panic: softdep_deallocate_dependancies cpuid = 1 It is an SMP machine, running a rather generic kernel, but with options QUOTA (quotas are active on a different volume, though). Sadly no DDB was configured, I'll try to reproduce this. Is snapshotting/dumping supposed to work on ggate/gmirrored devices? Uli
