Hi,
dmesg is probably useles:

Probably some logs after mounting...:

# dmesg | grep EXT
EXT3-fs (md2): mounted filesystem with ordered data mode
EXT3-fs (md2): using internal journal
EXT3-fs (dm-2): using internal journal
EXT3-fs (dm-2): mounted filesystem with ordered data mode
EXT4-fs (dm-8): mounted filesystem with ordered data mode. Opts:

(null)

quoted

EXT4-fs (dm-3): mounted filesystem with ordered data mode. Opts:

(null)

quoted

EXT4-fs (dm-12): mounted filesystem without journal. Opts: (null)
EXT4-fs (dm-8): re-mounted. Opts: commit=0
EXT4-fs (dm-3): re-mounted. Opts: commit=0
EXT4-fs (dm-12): re-mounted. Opts: commit=0

^^^ um, what's that all about?

That is some info about startup mounted filesystems. I have about 10-15 mountpoints.

In theory, according to the docs, that's the same as the default, I
guess.

and:

                } else if (token == Opt_commit) {
                        if (arg == 0)
                                arg = JBD2_DEFAULT_MAX_COMMIT_AGE;

ok, I guess it is.

On last few lines, there is some info about usb key used on thic

pc:

# dmesg | tail -n 30
sd 14:0:0:0: [sdg] Asking for cache data failed
sd 14:0:0:0: [sdg] Assuming drive cache: write through

...

Other lines from dmesg seems not relevant. Should I post them too?

Usually best to post all the data and let us sort it out, yes.

I have posted it a few minutes ago, but for comfort, my full dmesg is here:

PS: Writing to disk from jbd2/dm-3-8 still active (iotop shows it

still on top of I/O activity).

I have no serious data there, but if I could be helpfull in

bugreport, give me some info what to do.

Try running the dmesg command, and see if there's anything
interesting
there.  If you're not sure if it's interesting, send it to us and

we

can take a quick look at it.
