Package: nfs-common
Version: 1:1.2.8-9
Severity: normal
Dear Maintainer,
showmount does not show IPv6 clients.
Steps to reproduce:
1.) umount an NFS share on a client
2.) run "exportfs -f ; exportfs -a" to flush and re-read the kernel
export table on the server
3.) mount an NFS share on a client
4.) invoke "showmount" or "showmount -a" on the server -> no clients are listed
I tried different showmount invocations (being done on the NFS server
itself):
# showmount
Hosts on servername:
-> no further output
# showmount -a
All mount points on servername:
-> no further output
# showmount -a localhost
All mount points on localhost:
-> no further output
# showmount localhost
Hosts on localhost:
-> no further output
In the kernel export table, the clients with mounted shares are properly
listed:
# wc -l /proc/fs/nfsd/exports
27 /proc/fs/nfsd/exports
One example:
# grep "::166/128" /proc/fs/nfsd/exports
/s2/sw fd40:9dc7:b528:8::/64,fd40:9dc7:b528:8::166/128(rw,no_root_squash,sync,wdelay,uuid=8d45a057:f2b448b9:8c3d26e7:f3a00e68,sec=1)
At least from the kernel side everything is fine and the issue seems
somewhere within the nfs-common package.
