Re: HEALTH_WARN 6 requests are blocked

Patrick,

At the moment, you do not have any problems related to the slow query.

So ok, understand.

But what can I do if the scrubbing process hangs by one page since last night:

root@ceph01:~# ceph health detail
HEALTH_OK

root@ceph01:~# ceph pg dump | grep scrub
pg_stat    objects    mip    degr    misp    unf    bytes    log    disklog    state    state_stamp    v    reported    up    up_primary    acting    acting_primary    last_scrub    scrub_stamp    last_deep_scrub    deep_scrub_stamp
2.5cb    101    0    0    0    0    423620608    324    324    active+clean+scrubbing+deep    2015-05-11 23:01:37.056747    4749'324    4749:6524    [14,10]    14    [14,10]    14    4749'318    2015-05-10 22:05:29.252876    3423'309    2015-05-04 21:44:46.609791

Perhaps an idea?

best regards

Scrubbing greatly affects the I / O and can slow queries on OSD. For more information, look in the 'ceph health detail' and 'ceph pg dump | grep scrub'

Hi,

is that the reason for the Health Warn or the scrubbing notification?

thanks

regards

Hi, Patrik.

You must configure the priority of the I / O for scrubbing.

Hi,

the ceph cluster shows always the scrubbing notifications, although he do not scrub.

And what does the "Health Warn" mean.

Does anybody have an idea why the warning is displayed.

How can I solve this?

 cluster 78227661-3a1b-4e56-addc-c2a272933ac2
     health HEALTH_WARN 6 requests are blocked > 32 sec
     monmap e3: 3 mons at {ceph01=10.0.0.20:6789/0,ceph02=10.0.0.21:6789/0,ceph03=10.0.0.22:6789/0}, election epoch 92, quorum 0,1,2 ceph01,ceph02,ceph03
     osdmap e4749: 30 osds: 30 up, 30 in
      pgmap v2321129: 4608 pgs, 2 pools, 1712 GB data, 440 kobjects
            3425 GB used, 6708 GB / 10134 GB avail

                4607 active+clean
  client io 3282 kB/s rd, 10742 kB/s wr, 182 op/s

thanks

best regards
