Hi, I setup an encrypted disk cgd1 (aes-cbc 256 on top of wd0g, disklabel verification) with a dump device cgd1b but I can't dump to it (I enter ddb and type sync to dump). It prints "device bad".
If I enable CGDDEBUG and set cgddebug to 1, it prints some additional information (typing from a photo): dumping to dev 20,17 (offset=215879, size=3119109):getcgd_softc(0x1411): unit = 1 cgdsize(0x1411) cgdopen(0x1411, 0) getcgd_softc(0x1411): unit = 1 cgdclose(0x1411, 0) getcgd_softc(0x1411): unit = 1 dump cgddump(0x1411, 215879, 0xffff8000d6c3e000, 4096) getcgd_softc(0x1411, unit = 1 device bad With more verbose debugging it can hang instead of printing "device bad". For example, if I set cgddebug to 4 and mount cgd1e dumping to dev 20,17 (offset=215879, size=3119109):getcgd_softc(0x1411): unit = 1 cgdsize(0x1411) cgdopen(0x1411, 0) getcgd_softc(0x1411): unit = 1 getcgd_softc(0x1413): unit = 1 cgdstrategy(0xfffffe836f63b5a8): b_bcount = 512 cgd_diskstart(x0fffffe836f85cd08, 0xfffffe836f63b5a8) Is it expected to work at all?
