Greetings,
I was experimenting with zfs, and i made the following test, i shutdown the
computer during a write operation
in a mirrored usb storage filesystem.
Here is my configuration
NGS USB 2.0 Minihub 4
3 USB Silicom Power Storage Pens 1 GB each
These are the ports:
hub devices
/-------------------------------------------\
| port 2 | port 1 |
| c10t0d0p0 | c9t0d0p0 |
---------------------------------------------
| port 4 | port 4 |
| c12t0d0p0 | c11t0d0p0 |
\________________________/
Here is the problem:
1)First i create a mirror with port2 and port1 devices
zpool create myPool mirror c10t0d0p0 c9t0d0p0
-bash-3.2# zpool status
pool: myPool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
myPool ONLINE 0 0 0
mirror ONLINE 0 0 0
c10t0d0p0 ONLINE 0 0 0
c9t0d0p0 ONLINE 0 0 0
errors: No known data errors
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c5t0d0s0 ONLINE 0 0 0
errors: No known data errors
2)zfs create myPool/myfs
3)created a random file (file.txt - more or less 100MB size)
digest -a md5 file.txt
3f9d17531d6103ec75ba9762cb250b4c
4)While making a second copy of the file:
cp file.txt test &
I''ve shutdown the computer while the file was being copied. And
restarted
the computer again. And here is the result:
-bash-3.2# zpool status
pool: myPool
state: UNAVAIL
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from a backup source.
see: http://www.sun.com/msg/ZFS-8000-5E
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
myPool UNAVAIL 0 0 0 insufficient replicas
mirror UNAVAIL 0 0 0 insufficient replicas
c12t0d0p0 OFFLINE 0 0 0
c9t0d0p0 FAULTED 0 0 0 corrupted data
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c5t0d0s0 ONLINE 0 0 0
errors: No known data errors
-------------------------------------------------------------------
I was expecting that only one of the files was corrupted, not the all the
filesystem.
Thanks & Regards
Paulo

I haven''t tried another HUB yet but will eventually test the Adaptec XHub 4 (AUH-4000) which is on the HCL list...
Thommy, If I read correctly your post stated that the pools did not automount on startup, not that they would go corrupt.

But the data was there after I fiddled with the sticks and exported/imported the pool.
Did the same test again and here is the result: 1) zpool create myPool mirror c6t0d0p0 c7t0d0p0 2) -bash-3.2# zfs create myPool/myfs -bash-3.2# zpool status pool: myPool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM myPool ONLINE 0 0 0 mirror ONLINE 0 0 0 c6t0d0p0 ONLINE 0 0 0 c7t0d0p0 ONLINE 0 0 0 errors: No known data errors pool: rpool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c5t0d0s0 ONLINE 0 0 0 errors: No known data errors 3)Copy a file to /myPool/myfs ls -ltrh total 369687 -rwxr-xr-x 1 root root 184M Jun 3 22:38 test.bin 4)Copy a second file cp test.bin test2.bin & And shutdown Startup 5) -bash-3.2# zpool status pool: myPool state: UNAVAIL status: One or more devices could not be opened.

After getting frustrated and thinking about it for a while, I decided to test each MicroSD card and controller independently (using dd) and one of the adapters turned out to be flakey at just writing zeros. It also happened to be the #0 adapter which through me off for a while, since that''s where I started. So, then I was still having problems (but I had tested the remaining units), so I went home for the weekend, and left them plugged into their hubs (i-rocks brand seems OK so far), and came back to a system log full of a second adapter dropping out several times over the weekend (though it survived a quick dd). Taking it off the hub, it did the same thing for me if I waited long enough (10 minutes or so - I assume it was getting warmed up). I''ve also had to replace a server mobo which had a faulty USB implementation (Compaq brand, one of the early USB2.0 chips). Just food for thought - there''s a lot to go wrong before ZFS sees it and USB gear isn''t always well-made. -Bill ----- Bill McGonigle, Owner Work: 603.448.4440 BFC Computing, LLC Home: 603.448.1668 bill at bfccomputing.com Cell: 603.252.2606 http://www.bfccomputing.com/ Page: 603.442.1833 Blog: http://blog.bfccomputing.com/ VCard: http://bfccomputing.com/vcard/bill.vcf

Try doing "zpool export myPool" and "zpool import myPool" at this point, it should work fine and you should be able to get your data back.
