After some investigation, I notice that, if disable nfs/server manually,
it cannot enable again
# svcadm disable nfs/server
# svcadm enable nfs/server
# echo $?
0
# svcadm refresh nfs/server
# echo $?
0
# svcs -a | grep nfs
disabled 0:42:06 svc:/network/nfs/cbd:default
disabled 0:42:06 svc:/network/nfs/mapid:default
disabled 0:42:35 svc:/network/nfs/rquota:default
disabled 0:47:21 svc:/network/nfs/server:default
online 0:46:52 svc:/network/nfs/status:default
online 0:46:52 svc:/network/nfs/nlockmgr:default
online 0:46:52 svc:/network/nfs/client:default
# tail /var/svc/log/network-nfs-server:default.log
[ Jul 3 00:46:52 Stopping because service disabled. ]

No NFS filesystems are shared
/usr/sbin/sharemgr start -P nfs -a
# Start up mountd and nfsd if anything is exported.
if /usr/bin/grep -s nfs /etc/dfs/sharetab >/dev/null; then
startnfsd=1
fi
# If auto-enable behavior is disabled, always start nfsd
if [ `svcprop -p application/auto_enable nfs/server` = "false" ]; then
startnfsd=1
fi
I tried the above commands manually,
# /usr/sbin/sharemgr start -P nfs -a
# echo $?
0
# /usr/bin/grep -s nfs /etc/dfs/sharetab
# echo $?
2
# svcprop -p application/auto_enable nfs/server
true
So the issue may caused by /etc/dfs/sharetab not exist
If there're shared records, svcadm disable/enable will not hurt nfs/server,
but if there's no any shared records, nfs/server just cannot enable again.
The issue looks only happen on zfs /,
# zfs set sharenfs=on testpool.106430/testfs.106430
# svcadm disable nfs/server
# svcs -a | grep nfs/server
disabled 1:54:29 svc:/network/nfs/server:default
# svcadm enable nfs/server
# svcs -a | grep nfs/server
online 1:54:50 svc:/network/nfs/server:default
# share
-@testpool.106 /testdir106430 rw ""
# svcadm disable nfs/server
# share
# zfs set sharenfs=off testpool.106430/testfs.106430
# svcadm enable nfs/server
# svcs -a | grep nfs/server
disabled 1:55:31 svc:/network/nfs/server:default
Then, at that point, I could not share any legacy directory of ufs,
# mkdir /var/tmp/abc
# share /var/tmp/abc
Could not share: /var/tmp/abc: system error
# echo $?
32
