Hello,

thanks for new release.

by the way, I have been in trouble.
my /n/dump is something weird.

two monthes ago, there was a power outage with the sudden thunder.
I guess that made the problem.

hebe% 9fs dump
hebe% ls /n/dump
/n/dump/2015
/n/dump/2016
/n/dump/2017
/n/dump/2018
hebe% ls /n/dump/2018
/n/dump/2018/0101
/n/dump/2018/0102
...
/n/dump/2018/0903
/n/dump/2018/crc32
/n/dump/2018/gcpu
...
/n/dump/2018/zip

# I don't know why crc32 etc are shown there.
# perhaps they are files in /amd64/bin

hebe% ls /n/dump/2018/0706
...	# OK
hebe% ls /n/dump/2018/0707
ls: /n/dump/2018/0707: '/n/dump/2018/0707' does not exist

# 0706 is the last effective dump

Kernel message is:
checktag pc=3D2010df ow"/dev/sdE0/fscache"w"/dev/sdE1/fsworm"(c) =
tag/path=3DTdir/1233; expected Tdir/1

hebe% ls -lq /n

# the qid is something weird

hebe% 9fs dump
hebe% ls -lq /n

hebe%=20

I did 'check tag' in fs console, but nothing improved.

the weirdness comes from cwfs.

cfs dump
current fs is "dump"

fstat /2018/0706
name =3D 0706
uid =3D -1; gid =3D -1; muid =3D 0
size =3D 0; qid =3D 80000001/22
atime =3D 1530853210; mtime =3D 1530853210
dblock =3D 4415041 0 0 0 0 0; iblocks[0] =3D 0; iblocks[1] =3D 0; =
iblocks[2] =3D 0; iblocks[3] =3D 0

fstat /2018/0707
cant stat /2018/0707

should I reconstruct my file system?

any hint welcome!
