hi community .. have updated some gluster nodes from 3.5.0 to 3.5.2 and update seems to remove some file (saved to .rpmsave) and glusterd is killed, but not restarted .. so having to restart glusterd after each node update. is that expected ? |

Arrfab: I think there is a bug about that... |
| 07:54 |
Arrfab |
ndevos: well, the rpm postinstall scriplet kills glusterd but doesn't do anything else .. |
| 07:55 |
Arrfab |
I mean, not related to even try to restart glusterd if it was running .. not even cleaning the pid file, meaning that a simple 'service glusterd status' complains about 'glusterd dead but subsys locked' |
| 07:55 |
ndevos |
Arrfab: uh... it should start glusterd again, there was a bug where glusterd got started before the previous glusterd exited - that caused the 2nd glusterd to fail starting |

Hi i need help |
| 14:02 |
mojeime_ |
I created Striped Replicated Volumes |
| 14:03 |
mojeime_ |
using this command : gluster volume create test-volume stripe 2 replica 2 server1:/exp1 server2:/exp3 server3:/exp2 server4:/exp4 |
| 14:04 |
mojeime_ |
now when i mount volume on client machine and make test file there on server 1 and 2 everything is ok but on server 3 and 4 file shows but it is 0 bytes? |
| 14:04 |
mojeime_ |
Any help on this? |
| 14:06 |
ndevos |
mojeime_: it depends on the size of the file you are creating, also ,,(stripe) has some more details |
| 14:06 |
glusterbot |
mojeime_: Please see http://joejulian.name/blog/should-i-use-stripe-on-glusterfs/ about stripe volumes. |
| 14:07 |
mojeime_ |
I did red that |
| 14:07 |
mojeime_ |
if i put on mount folder some big tar for example |
| 14:07 |
mojeime_ |
it shows up on every server without problem |
| 14:08 |
mojeime_ |
only small files shows on every server but on server 3 and 4 they are 0 bytes |
| 14:08 |

mojeime_: there are also ,,(link files), maybe you are seeing those? |
| 14:31 |
glusterbot |
mojeime_: I do not know about 'link files', but I do know about these similar topics: 'linkfile' |
| 14:31 |
ndevos |
@linkfile |
| 14:31 |
glusterbot |
ndevos: A zero-length file with mode T--------- on a brick is a link file. It has xattrs pointing to another brick/path where the file data resides. These are usually created by renames or volume layout changes. |
| 14:32 |
mojeime_ |
i don think that is the case |
| 14:33 |
mojeime_ |
is stripe supose to divide the file accross the servers or keep file size? |
| 14:36 |
ndevos |
stripe will split files in smaller pieces and distributes the pieces (one file with multiple 'chunks') over the bricks |
| 14:36 |
ndevos |
distribute would just spread the complete files over the different bricks |
| 14:37 |
ndevos |
but, thats pretty well explained in ,,(stripe), which you have read... if that post is not clear enough, leave a comment in the blog or tell JoeJulian here |
| 14:37 |

the worst part was that those threads were zombified, sorta |

even killing the JVM would not free the resources |
| 19:36 |
semiosis |
couldn't release the tcp socket |
| 19:36 |
semiosis |
couldn't free the memory |
| 19:36 |

had to restart the whole VM |
| 19:36 |
semiosis |
never seen anything like that in a JVM |
| 19:37 |
semiosis |
this was a tomcat server |
| 19:45 |
JoeJulian |
semiosis: Could have killed glusterfs, which would kill the mount of course, and that would have unzombied them I think. |
| 19:45 |

ah right |

i expanded half of the bricks, and glustershd was hitting them pretty hard, presumably causing clients to starve |
| 19:47 |
semiosis |
now i get to try again with the other half :) |
| 19:48 |
JoeJulian |
You took it down when you expanded the brick? |
| 19:48 |
JoeJulian |
I've always left it up. |
| 19:49 |
semiosis |
yep, using EBS, have to detach the existing EBS volume & replace it with a larger one restored from a snapshot |
| 19:49 |
JoeJulian |
Oh, right |
| 19:49 |
semiosis |
so, kill glusterfsd, unmount, detach, create, mount, grow, restart glusterfsd |

Mine's always gone, lvresize, xfsgrow, done. |
| 19:51 |
semiosis |
on the wiki perhaps |
| 19:52 |
semiosis |
yep, that's too risky for me |
| 19:52 |
semiosis |
i like to have a solid fallback plan |
| 19:53 |
semiosis |
if anything goes wrong, i just restore the whole server from the snapshot |
| 19:54 |
semiosis |
hmmmm, maybe if i had done this serially, one brick at a time, it would've been smoother. |
| 19:55 |
semiosis |
instead of half the volume at once |
| 19:55 |
JoeJulian |
Seems likely. |
| 19:56 |
JoeJulian |
Also remember, once your background-self-heal queue is full, any subsequent files are going to hang your client until they're healed. |

I wonder why it's hitting it so hard... |
| 21:24 |

i dont understand all the stuff in the shd log, but it's the server that stayed up that has all the activity in the shd log, and on the other server the bricks that went down & got expanded are slammed |
| 21:25 |
semiosis |
if i strace one of the hot brick daemons i see a lot of futex wait/wake |

How terrible is it, to aws sync the underlying gluster filesystem directly (instead of the view as mounted by a client)? |
| 22:21 |
semiosis |
aws sync? |
| 22:22 |

Ie-- if we wanted to do a nightly sync of the data to AWS S3 (ie, read-only), would that be OK? |

Howdy! I have a dumb question... The other day I mounted a glusterfs volume on a machine and during heavy use the logfile eventually filled up my root partition. Does anyone know how to mount with logging disabled? Or should I set up a logrotate config to trim the fat every couple of minutes? |
| 22:22 |
semiosis |
nbvfuel: is your glusterfs volume in EC2? on EBS bricks? you can use the CreateImage API call to snapshot the whole server |
| 22:23 |
semiosis |
m0rph: you can set log level with the diagnostics.log-level ,,(options) |
| 22:23 |
glusterbot |
m0rph: See config options and their defaults with 'gluster volume set help'; you can see the current value of an option, if it has been modified, with 'gluster volume info'; see also this page about undocumented options: http://goo.gl/mIAe4E |
| 22:23 |
nbvfuel |
semiosis: No, it's on hardware outside of the AWS ecosystem. The rsync would be for offsite DR. |
| 22:23 |
semiosis |
ohhh |
| 22:24 |
semiosis |
nbvfuel: you might as well just sync from a glusterfs client mount point to s3 then |
| 22:24 |
semiosis |
that's how you'd have to restore the data, in the reverse direction |
| 22:25 |
m0rph |
semiosis: Didn't know about that setting. I'll check that out, thank you. |
| 22:25 |
nbvfuel |
semiosis: OK. For speed of read, I wasn't sure if reading from the brick directly was kosher. |
| 22:25 |
JoeJulian |
m0rph: 1st, this is why you should always make /var/log its own partition. 2nd, my home directory mount used a whopping 9k yesterday. What the heck is happening in your logs? |
| 22:25 |
semiosis |
nbvfuel: you might consider using lvm snapshots then storing a whole lv image to s3 |
| 22:26 |
semiosis |
nbvfuel: your speed probably will be limited by your s3 bandwidth, not your disk bandwidth |
| 22:27 |

nbvfuel: someone just contributed a patch to it, shockingly |
| 22:27 |
nbvfuel |
semiosis: hmm, OK. It's not the full filesystem, just a few important directories. |
| 22:27 |
semiosis |
oh then never mind |
| 22:28 |
m0rph |
JoeJulian: /var/log in a partition is a good idea, but I don't have that many logs usually. As for what was going on, I was rsyncing ~6TB. Maybe my logging level was too verbose for that much activity? |
| 22:29 |
nbvfuel |
I guess my question was potentially a more general of: "is it stupid of me to think that I can read from the gluster file system directly, instead of from a client mount" |
| 22:29 |
JoeJulian |
I couldn't tell without seeing it, but that still shouldn't make that big of a log. |
| 22:29 |
semiosis |
it shouldn't hurt, but i dont think it will help either |
| 22:29 |

nbvfuel: ^ |

I don't have the log anymore unfortunately. |

A different question.. With regards to the "performance cache" translator. How smart is the refresh timeout? The default is 1sec; does that mean that after 1 second it frees the memory it's using to get fresh data? Or does it verify the data is still the same to avoid having to reload the same again the following second? |
| 22:35 |
m0rph |
In a read-heavy environment, should I set it to a few seconds? or is that a bad idea? |
