has anybody else faced complete freezes of a machine due raid-check? today the same as last thursday while the freeze seems not to happen by the raid-check itself according to running smokepings from outside which are green until i try to use the machine
* last thursday morining around 8:30 while login in KDE * today around 9:45 AM while power on the screen and continue to re-use a existing KDE session
however, after hard power off, the fsck, login in KDE and start the raid-check manually on TTY3 it continues ____________________________________________________
since the raid-check starts at 5:30 and all heavy IO from remote-backups and rsnapshot ends at 4:30 to not collide it's hardly IO-dependent
[root@srv-rhsoft:~]$ cat /etc/cron.d/raid-check 30 5 * * Thu root /usr/sbin/raid-check

I had something similar happen in pre-release kernels a few versions ago, but it got fixed and I am not seeing it now.

interesting - thanks for feedback
i have faced this only on F20 with the recent 3.14 kernel which is except the weekly raid-check hyperstable under any heavy networking and/or IO load, what makes it hard to debug is that it's not triggerable by starting raid-check manually
the only information i sadly can provide is partitioning / raid setup

The bug I reported to upstream is: https://bugzilla.kernel.org/show_bug.cgi?id=68061
That was for 3.13, so if you were running into a varient of the problem I was seeing, you should have seen it in 3.13. I did not see the problem with 3.14 or 3.15 pre-release kernels. I'm using raid 1 instead of raid 10.

different problem class you where able to look at cat/proc/mdstat
in my case the machine is just dead and don't react on any input including ACPI powerbutton, this morning i saw a frozen KDE desktop with high CPU load from the past in monitoring widgets, last week it froze while login (after enter username and password in KDM the first black screen before build the desktop appeared and any operatins stopped)
i will wait some hours for possible feedback here and than file a bugreport, sadly there is not much constrcutive i can report caused by the complete system freeze and no logs or anything after hard power off and boot again

ok, it's not only raid-check, 15 minutes ago it happened again freeze number 3 - i fear a bugreport makes not much sense because "system freezes once or two per week before lunch" is not that much helpful, most likely that will not hit only me and get away with a following 3.14.x update

commit 0bc4091108e8f2e65faef3082e5261f2c35cd2b4 Author: NeilBrown neilb@suse.de Date: Tue May 6 09:36:08 2014 +1000
md: avoid possible spinning md thread at shutdown.
commit 0f62fb220aa4ebabe8547d3a9ce4a16d3c045f21 upstream.
If an md array with externally managed metadata (e.g. DDF or IMSM) is in use, then we should not set safemode==2 at shutdown because:
1/ this is ineffective: user-space need to be involved in any 'safemode' handling, 2/ The safemode management code doesn't cope with safemode==2 on external metadata and md_check_recover enters an infinite loop.
Even at shutdown, an infinite-looping process can be problematic, so this could cause shutdown to hang.

commit 8c7311a1c4a8d804bde91b00a2f2c1a22a954c30 Author: NeilBrown neilb@suse.de Date: Mon May 5 13:34:37 2014 +1000
md/raid10: call wait_barrier() for each request submitted.
commit cc13b1d1500656a20e41960668f3392dda9fa6e2 upstream.
wait_barrier() includes a counter, so we must call it precisely once (unless balanced by allow_barrier()) for each request submitted.
Since commit 20d0189b1012a37d2533a87fb451f7852f2418d1 block: Introduce new bio_split() in 3.14-rc1, we don't call it for the extra requests generated when we need to split a bio.
When this happens the counter goes negative, any resync/recovery will never start, and "mdadm --stop" will hang.

I can confirm the above on two machines w/ MD RAID10 (and boot on MD RAID1).
Thus far, I've yet to see machines w/ RAID5 or RAID6 exhibit the same crash.

According[1] to NeilBrown it's resolved and applied in the 3.14.6[2]. If the problem is still present, you can continue the discussion on linux-raid@vger.kernel.org[3]. Don't forget to CC here, or vice versa.

According[1] to NeilBrown it's resolved and applied in the 3.14.6[2]. If the problem is still present, you can continue the discussion on linux-raid@vger.kernel.org[3]. Don't forget to CC here, or vice versa.
i really stressed my office-machine over the last few days by move many gigabytes of data while raid-ckechk was running and *both* issues (the frezze at raid-check and hang at shutdown) seems to be fixed with 3.14.6
well, since i closed both reported bugs with 3.14.5 followed by re-open both with a few hours i will look at that a few days
however, since 3.13 was EOL there was nothing really wrong with the updates push given the the security relevant fixes and using kernels from koji over years the first time with real troubles is not that bad

sadly both re-opened today, after some hours of running shutdown and raid-check with 3.14 is a pain and taht is *for sure* 3.14.x because my co-developer stayed at the last 3.13 until i thought it's fine now, had never that problems and both 3.14.x shutdowns freezed with mdraid
I can confirm the above on two machines w/ MD RAID10 (and boot on MD RAID1).
Thus far, I've yet to see machines w/ RAID5 or RAID6 exhibit the same crash.

I'm currently running a full RAID check on 8TB RAID10 volume w/ 3.14.6. Thus far, everything seems to be working just fine (knock wood).
