Hello All.
I've got a time-to-time reproducible panic while running cleanups on a
mirror built with hammer mirror-stream.
I'm running a system built on -DEVELOPMENT sources from August, 9th
(uses SILI device) and a following system layout:

/dev/da0s1a / ufs rw 1 1
/dev/da0s2b none swap sw 0 0
/dev/da0s2h /HAMMER0 hammer rw 2 2
/HAMMER0/pfs/var /var null rw 2 2
/dev/da1s1a /mirror ufs rw 1 1 # not used
/dev/da1s2b none swap sw 0 0
/dev/da1s2h /HAMMER1 hammer rw 2 2
/HAMMER1/pfs/var /mirrorvar null rw 2 2
proc /proc procfs rw 0 0

A kernel panic occurs on running daily cleanups on a slave part of
mirror and I managed to reproduce it manually while executing %hammer
reblock and %hammer rebalance commands on a slave pfs after a day or two
of uptime.
When running %hammer cleanup immediately after system boot-up, it always
runs fine and resumes with no error.
I've attached a screenshot of a latest panic I've got while running
cleanup.

If there can be any solution for this problem?

Which kernel version are you running? Please post a uname -a output.

Also, please configure a dumpdev and capture a crash dump.

The system was upgraded from DragonFly 1.8-Release.

Also, please configure a dumpdev and capture a crash dump.

O.K. Now I have to wait a number of days to get panic again.

Updated by dfuser over 15 years ago

Hello again.

Before updating I've decided to run %hammer reblock on a slave pfs with
%hammer reblock /mirrorvar
without remounting it before executing a command and got next (reported
with kgdb):

Best update to latest master, there were many fixes since August.

Now I'm planning to start updating the system and watch if crashes will
go on. Please tell, what can I dig from crash dumps more, or how to send
those dumps to You?

Hi!

I had something very similar on 95% full hammer FS with version of FS = 1.
After upgrading it to v2 panics vent away.

are you sure this is new code? because there is no version tag. uname
should look like this these days:

Hi!

I had something very similar on 95% full hammer FS with version of FS = 1.
After upgrading it to v2 panics vent away.

dennis@dfly (xterm) > uname -srip
DragonFly 2.3.1-DEVELOPMENT i386 GENERIC
As of 05/Jul/2009

Like:
  1. hammer version-upgrade /mnt/big_plate 2

Also here are some interesting lines in /var/log/messages, possibly
indicating corrupted media:

As I can understand, I have a 2nd version of filesystem:

diana# hammer version /mirrorvar
min=1 wip=3 max=2 current=2 description="2.3 - New directory entry layout"
available versions:
1 NORM 2.0 - First HAMMER release
2 NORM 2.3 - New directory entry layout

and the logfile has nothing indicating any disk problems. And the system
has considerably small percent of space usage (3% after daily cleanup,
about 15% before)

Sorry, I've updated not to a [src-master.tar.bz2 (15-Sep-2009 17:07)],
but to [src-Devel.tar.bz2 (13-Sep-2009 15:05)].
Now I'll try to re-update.

Oh nevermind. The version output only works if you are using git (which you should)

Hi!

Ok, this means we have/had different problems. I've upgraded to latest
master today (almost equal 2.4-Release). That's all I could help you.

Side note: Much better overall experience. No stalls on rl0 interface
(was not sure about the source of the problem) and smoother
everything. Thanks, folks!

Gotta be two different things.  Basically ad4 had a DMA error and
    detached and the HAMMER filesystem, being unable to write, threw a fit.
    That would be an issue with NATA.  HAMMER was just saving itself.
That sort of UDMA failure is usually indicative of an IDE wiring
    issue.
We did fix a bug in HAMMER related to very rare incorrect B-Tree
    deletions which would lead to lost inodes and potentially panics.
    Anything like that should no longer occur.

Wiring was the one possibility, and underpowered drive could be just
another (P4/2.4 with 3 HDD's on noname 300W PSU). Just realized that
few days ago: mbmon's 12P had showed 10.5+ Volts until PSU was
replaced with 400W one.

PS. That also saves my ears in the night, thanks to 120mm cooler :)

Hi Dennis,

From your last email I would assume you fixed it by replacing either the wire or
the PSU (or both). Is that correct?

Cheers,

- There was a fix by Matt for related issues.
- DMA errors that could indicate cable issues, if not problems in the drive itself.

Closing this one.
