11:30 jiffin ndevos: for normal volume, dht filters out T files and gives back only the normal files to the client
11:38 Manikandan joined #gluster-dev
11:48 ndevos jiffin: ok, thanks, so no need to backport those gNFS changes to 3.6 and 3.5
11:49 ndevos jiffin: I wonder why tiering does not handle it the same way though... migration would be similar to rebalance
11:52 jiffin ndevos: yes ,the backpor is not required.
11:52 jiffin s/backpor/backport
11:54 jiffin ndevos: I am not the right person to answer your second question :)
11:54 ndevos jiffin: hehe, yes, I know :)
11:54 ndevos dlambrig might be though!
11:55 jiffin ndevos: should be
12:00 overclk joined #gluster-dev
12:07 pppp joined #gluster-dev
12:10 skoduri ndevos, from what I understand while talking to Nithya on this, during migration readdir is performed on all subvols.. so if they filter out 'T' files, they sure will read the original files in another subvol..
12:10 skoduri but for tiering to improvise ls/readdir performance, they choose to read only from cold tier
12:10 skoduri which can have 'T' files but not original files
12:11 ndevos skoduri: aha, ok!
12:12 ndevos wait, the cold (slow) tier is used for readdir? sounds strange to me, I would expect that the hot (fast) tier would be used?
12:13 ndevos does the hot tier not have the T-files for cold contents?
12:13 ndevos skoduri, dlambrig: ^
12:13 skoduri ndevos, that's because cold tier is sure to contain all the files unlike hot tier which contain only the accessed ones
12:14 ndevos skoduri: hmm, I expected the hot tier to have T-files for migrated contents, but maybe that is not the case then
12:15 skoduri that's because when you attach a tier, we shall not migrate all the files except for the ones which are being accessed to hot tier..
12:15 skoduri at least that's my understanding ;-)
12:16 ndevos oh, that could be, I guess you attach a hot-tier to a volume, not a cold-tier
12:16 skoduri right
12:16 firemanxbr joined #gluster-dev
12:17 ndevos dlambrig: https://github.com/gluster/glusterfs-s​pecs/blob/master/done/Features/tier.md could use an update with details about T-files for readdir and maybe also steps that are done during migration

13:06 dlambrig ndevos: I’ll take a look at that. Thanks.
13:09 ndevos dlambrig: thanks!
13:12 dlambrig ndevos: skoduri has described the problem we had correctly. We had to make the cold subvolume the hashed subvolume for technical reasons. Yes this incurs some performance penalty and also led to the side effect with NFS. Yeah, can update documentation describing the reasons behind this.
13:14 ndevos dlambrig: yeah, I understand, and updating the doc is much appreciated

13:51 kkeithley glusterfs logs using 8G (of 43G).  I don't think we need logs from 2014 or 1st half of 2015
13:51 ndevos those precious logs!
13:52 kkeithley yessss, my preciousss. We needssss to keepssss the preciousssss logsssss
13:52 spalai left #gluster-dev
13:53 * kkeithley wonders how many other slaves are close to filling up their disks
13:53 ndevos doesnt csim have a munin server running somewhere?
13:54 kkeithley munin?
13:54 ndevos like nagios or zabbix, I think
13:54 kkeithley don't knwo
13:54 kkeithley know
13:55 ndevos I thought he did, but I dont know the hostname
13:56 * ndevos tried status.gluster.org, and failed hard
13:59 kkeithley besides precious logs, /var/cache/mock is the biggest user, epel-6, epel-7, fedora-20 (srsly?) and fedora-22.
14:03 ndevos you can delete all the subdirs under /var/cache/mock, it'll get downloaded on demand anyway
14:03 ndevos funny that there is no fedora-21?

15:19 kkeithley oh, oka
