Do you have a sightly more specific hint? I might be missing out on the correct keyword that described this functionality. Thanks.

Hey there,

I've used google, looked up CUPS website, but no result.
Is there an option to not print between certain times?
Let's say prints during the night are queued but not send to the print...

Look at SMART using smartctl.

I fixed a very similar problem this way:
- Download the latest version of the problem giving package(s) as deb. In your case linux-headers-generic and libgtkmm-2.4-1c2a.
- Force this package(s) to...

Correct. This I forgot:

Edit /lib/udev/rules.d/64-md-raid.rules

Comment out the line saying "ACTION=="add", RUN+="/sbin/mdadm --incremental $tempnode""

Now auto assembly is disabled.

When something goes corrupt...there is a reason most times...

Start by looking up the S.M.A.R.T. statuses for the disks.

Maybe the boot process is faster in 13.10. And so the drives could be not ready.

If you want, you can do a manual assembly later in the boot process by putting the assemble command in...

LiveCD definitely is the way to go!

Okay. I don't know why normal mount isn't working. Maybe the filesystem is corrupt already.

You may try this:...

Just with the normal mount command to a location inside the root (/).

Edit:
Ah page 2 and you've got the mount command. Good.

Try with the t flag.
Like

mount -t ext4 /dev/sdb6 /temporary

Is S.M.A.R.T. okay for these disks? You replaced the bad ones?

Do you have non raid partitions or space on the disks for individual testing?

You don't need to remove them because they are currently not in an array. They are like ghost members or so.

Yes mount them as they were non-raid drives, get missing stuff of them, then...

/dev/sdc is okay. If UDMA_CRC_Error_Count is increasing, you need to replace the SATA data cable.
What about the others?

Concerning /dev/md0...
/dev/sdc1 believes it is an array member, while I...

Something went wrong with the SMART logs, please post again. You may post inline using the code-tag.

Concerning raid, definitely something strange going on.
Looking at the examine's, RAID5 is...

Aah my bad. Put the commands in a bash script and run it as root.
Maybe the failure of drop cache explains your higher read. At this moment the difference between read and write is too much. Current...

After rebuild the disks should be almost identical, so you won't find your lost files based on raid level.

So you need to find out whats up here...
Begin with reading S.M.A.R.T. for each disk.

If your array is tuned well, ethernet indeed will be the bottleneck.

I don't know the performance drop...there is some information about this on the web.

Use this to quickly test your array...

parted /dev/sdb align-check m 1

m = minimal, it checks for 4k alignment
o = optimal, it checks for 1M alignment

1 = partition number on device.

If there is no alignment, performance may...

Gpt?

That's strange. Maybe try a older distro.

/dev/sdb seem to be broken indeed.

Unless anyone else has a better idea I suggest to rescue this disk to a new one and try from there. Rescuing a disk is a special process that's not the same as a...

Yeah that was what I was thinking...

Good find on the kernel. My knowledge doesn't go there but will browsing the file I saw that the I/O scheduler might be different. I can't help any further if...

You can do what you probably did when you built the current array. Start the array degraded with one member. If you think...

Did you apply the dirty writeback centisecs tweak or is data intercepted before this?
