got something interesting? :)

Hi,

I'm sorry, I had no time to make tests yesterday. Am starting to do them now. So soon I'll reply.

2014-10-18 19:29 GMT+03:00 Roman <romeo.r@xxxxxxxxx>:
This volume is now being tested by my collegue for windows purposes.
I will create new one on monday and will test with parameters you've sent me.

2014-10-17 17:36 GMT+03:00 Pranith Kumar Karampuri <pkarampu@xxxxxxxxxx>:
Roman,
Everything in the logs look okay to me, except the following profile number:
      3.91 1255944.81 us     127.00 us 23397532.00 us            189       FSYNC

It seems that at least one of the fsyncs is taking almost 23 seconds to complete. According to all the data you gave till now, I feel this is the only thing I feel could have done it. To test this bit, could you turn off the following option using and try again?

gluster volume set <volname> cluster.ensure-durability off

Let me know what happened. I am extremely curious to here about it.

Pranith

ok. done.
this time there were no disconnects, at least all of vms are working, but got some mails from VM about IO writes again.

WARNINGs: Read IO Wait time is 1.45 (outside range [0:1]).
 This warning says 'Read IO wait' and there is not a single READ operation that came to gluster. Wondering why that is :-/. Any clue? There is at least one write which took 3 seconds according to the stats. At least one synchronization operation (FINODELK) took 23 seconds. Could you give logs of this run? for  mount, glustershd, bricks.

here is the output

does it make something more clear?

i think i may know what was an issue. There was an iscsitarget service runing, that was exporting this generated block device. so maybe my collegue Windows server picked it up and mountd :) I'll if it will happen again.

2014-10-13 20:27 GMT+03:00 Roman <romeo.r@xxxxxxxxx>:
So may I restart the volume and start the test, or you need something else from this issue?

hmm,
seems like another strange issue? Seen this before. Had to restart the volume to get my empty space back.

no file, but size is still 901G.
Both servers show the same.
Do I really have to restart the volume to fix that?
 IMO this can happen if there is an fd leak. open-fd is the only variable that can change with volume restart. How do you re-create the bug?

Sure.
I'll let it to run for this night .

hi Roman,
     Do you think we can run this test again? this time, could you enable 'gluster volume profile <volname> start', do the same test. Provide output of 'gluster volume profile <volname> info' and logs after the test?

Could you give your 'gluster volume info' output?

Hi,

I've got this kind of setup (servers run replica)


@ 10G backend
gluster storage1
gluster storage2
gluster client1

@1g backend
other gluster clients

Servers got HW RAID5 with SAS disks.

So today I've desided to create a 900GB file for iscsi target that will be located @ glusterfs separate volume, using dd (just a dummy file filled with zeros, bs=1G count 900)
For the first of all the process took pretty lots of time, the writing speed was 130 MB/sec (client port was 2 gbps, servers ports were running @ 1gbps).
Then it reported something like "endpoint is not connected" and all of my VMs on the other volume started to give me IO errors.
Servers load was around 4,6 (total 12 cores)

Maybe it was due to timeout of 2 secs, so I've made it a big higher, 10 sec.

Also during the dd image creation time, VMs very often reported me that their disks are slow like

WARNINGs: Read IO Wait time is -0.02 (outside range [0:1]).

Is 130MB /sec is the maximum bandwidth for all of the volumes in total? That why would we need 10g backends?

HW Raid local speed is 300 MB/sec, so it should not be an issue. any ideas or mby any advices?


Maybe some1 got optimized sysctl.conf for 10G backend?

mine is pretty simple, which can be found from googling.


just to mention: those VM-s were connected using separate 1gbps intraface, which means, they should not be affected by the client with 10g backend.


logs are pretty useless, they just say  this during the outage


[2014-10-13 12:09:18.392910] W [client-handshake.c:276:client_ping_cbk] 0-HA-2TB-TT-Proxmox-cluster-client-0: timer must have expired

[2014-10-13 12:10:08.389708] C [client-handshake.c:127:rpc_client_ping_timer_expired] 0-HA-2TB-TT-Proxmox-cluster-client-0: server 10.250.0.1:49159 has not responded in the last 2 seconds, disconnecting.

[2014-10-13 12:10:08.390312] W [client-handshake.c:276:client_ping_cbk] 0-HA-2TB-TT-Proxmox-cluster-client-0: timer must have expired

so I decided to set the timout a bit higher.

So it seems to me, that under high load GlusterFS is not useable? 130 MB/s is not that much to get some kind of timeouts or makeing the systme so slow, that VM-s feeling themselves bad.

Of course, after the disconnection, healing process was started, but as VM-s lost connection to both of servers, it was pretty useless, they could not run anymore. and BTW, when u load the server with such huge job (dd of 900GB), healing process goes soooooo slow :)
