I had a try increasing the debug-level of my nfs daemon: echo 32767 >/proc/sys/sunrpc/nfs_debug echo 32767 >/proc/sys/sunrpc/nfsd_debug
In dmesg I get: NFSD: laundromat service - starting NFSD: laundromat_main - sleeping for 90 seconds nfsd_dispatch: vers 3 proc 0 exp_export: export of invalid fs type. nfsd: exp_rootfh(/data [c77fa254] 192.168.1.1/24:unionfs/278) nfsd: exp_rootfh export not found. Any idea why the export is of invalid type and the export is not found? Mounting one of the directories that are part of my unionfs succeedes and dmesg shows: NFSD: laundromat service - starting NFSD: laundromat_main - sleeping for 90 seconds nfsd_dispatch: vers 3 proc 0 nfsd: exp_rootfh(/data1 [c7cfee94] 192.168.1.1/24:hdc/2) nfsd: fh_compose(exp 16:00/2 ///, ino=2) nfsd_dispatch: vers 3 proc 0 nfsd_dispatch: vers 3 proc 19 nfsd: FSINFO(3) 12: 00000001 00001600 00000002 00000000 00000000 00000000 nfsd: fh_verify(12: 00000001 00001600 00000002 00000000 00000000 00000000) nfsd: Dropping request due to malloc failure! found domain 192.168.1.1/24 found fsidtype 0 found fsid length 8 Path seems to be </data1> Found the path /data1 nfsd_dispatch: vers 3 proc 19 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
