Solaris 10 Generic_141444-09 V490
My autofs started hang up on
2962/1: lstat64("/net/niag2/opt", 0xFFBFFAD0) (sleeping...)
So I tried to restart it with
svcadm restart autofs
then autofs gone to maintanance state, and wrote to log
umount: /net/niag2/opt busy
>::fsinfo ! grep /net/niag2/opt
0000060047c39800 autofs /net/niag2/opt
> 0000060047c39800::print vfs_t vfs_data| ::print fninfo_t fi_rootvp | ::print
> vnode_t
{
v_lock = {
_opaque = [ 0 ]
}
v_flag = 0x1
v_count = 0x2 << Here it comes
v_data = 0x6004f9bf0c0
v_vfsp = 0x60047c39800
v_stream = 0
v_type = 2 (VDIR)
v_rdev = 0xffffffffffffffff
v_vfsmountedhere = 0
v_op = 0x60046c56ac0
v_pages = 0
v_npages = 0
v_msnpages = 0
v_scanfront = 0
v_scanback = 0
v_filocks = 0
v_shrlocks = 0
v_nbllock = {
_opaque = [ 0 ]
}
v_cv = {
_opaque = 0
}
v_locality = 0
v_femhead = 0
v_path = 0x6004f387a38 "/net/naig2/opt"
v_rdcnt = 0
v_wrcnt = 0
v_mmap_read = 0
v_mmap_write = 0
v_mpssdata = 0
v_scantime = 0
v_mset = 0
v_msflags = 0
v_msnext = 0
v_msprev = 0
v_mslock = {
_opaque = [ 0 ]
}
}
But

Nobody holds that vnode, so how it can have v_count = 2, and how can i find the
bad guy who won't like to call VN_RELE?
