Hot Tier
Hi,
We will look into the " failed to get index" error.
It shouldn't affect the normal working. Do let us know if you face any
other issues.
Regards,
Hari.

Hello
I reattached hot tier to a new empty EC volume and started to copy data to
the volume.
Good news is I can see files now on SSD

Hot Tier
For the tier daemon to migrate the files for read, few performance
translators have to be turned off.
By default the performance quick-read and io-cache are turned on. You
can turn them off so that
the files will be migrated for read.

You have missed the log files.
Can you attach them?

Hot Tier
Hi
At this point I already detached Hot Tier volume to run rebalance. Many
volume settings only take effect for the new data (or rebalance), so I
thought may this was the case with Hot Tier as well. Once rebalance
finishes, I'll re-attache hot tier.
cluster.write-freq-threshold and cluster.read-freq-threshold control number
of times data is read/write before it moved to hot tier. In my case

Hot Tier
Hi,
Before you try turning off the perf translators can you send us the following,
So we will make sure that the other things haven't gone wrong.
can you send us the log files for tier (would be better if you attach
other logs too),
the version of gluster you are using, the client, and the output for:
gluster v info
gluster v get v1 performance.io-cache
gluster v get v1

Hot Tier
Hi,
If it was just reads then the tier daemon won't migrate the files to hot tier.
If you create a file or write to a file that file will be made
available on the hot tier.

Blocking IO when hot tier promotion daemon runs
Thanks for the info, Hari. Sorry about the bad gluster volume info, I
grabbed that from a file not realizing it was out of date. Here's a current
configuration showing the active hot tier:

Why files goes to hot tier and cold tier at same time
Hi,
The actual data will be in the hot tier only till demotion. The file
that you see on the cold tier is just a linkto file of the file on the
hot tier.
These linkto file are necessary for the internal working of the tier.

Blocking IO when hot tier promotion daemon runs
I should add that additional testing has shown that only accessing files is
held up, IO is not interrupted for existing transfers. I think this points
to the heat metadata in the sqlite DB for the tier, is it possible that a
table is temporarily locked while the promotion daemon runs so the calls to
update the access count on files are blocked?

Blocking IO when hot tier promotion daemon runs
Hi Tom,
The volume info doesn't show the hot bricks. I think you have took the
volume info output before attaching the hot tier.
Can you send the volume info of the current setup where you see this issue.
The logs you sent are from a later point in time. The issue is hit
earlier than the logs what is available in the log. I need the logs
from an earlier time.
And along with the entire tier

Blocking IO when hot tier promotion daemon runs
The sizes of the files are extremely varied, there are millions of small
(<1 MB) files and thousands of files larger than 1 GB.
Attached is the tier log for gluster1 and gluster2. These are full of
"demotion failed" messages, which is also shown in the status:

Hi,
Can you send the volume info, and volume status output and the tier logs.
And I need to know the size of the files that are being stored.

Fwd: Ignore failed connection messages during copying files with tiering
Hi,
We create a GlusterFS cluster with tiers. The hot tier is
distributed-replicated SSDs. The cold tier is a n*(6+2) disperse volume.
When copy millions of files to the cluster, we find these logs:
W [socket.c:3292:socket_connect] 0-tierd: Ignore failed connection attempt
on /var/run/gluster/39668fb028de4b1bb6f4880e7450c064.socket, (No such file

Tiering Volumns
Hello everyone.
I have a new GlusterFS setup with 3 servers and 2 volumes. The "HotTier"
volume uses Nvme and the "ColdTier" volume uses HDD's. How do I specify the
tiers for each volume?
I will be adding 2 more HDDs to each server. I would then like to change
from a Replicate to Distributed-Replicated. Not sure if that makes a
difference in the tiering setup.

Failed to get quota limits
Hi,
Thanks for the link to the bug. We should be hopefully moving soon onto 3.12 so I guess this bug is also fixed there.
Best regards,

Failed to get quota limits
Dear Hari,
Thank you for getting back to me after having analysed the problem.
As you said I tried to run "gluster volume quota <VOLNAME> list <PATH>" for all of my directories which have a quota and found out that there was one directory quota which was missing (stale) as you can see below:
$ gluster volume quota myvolume list /demo.domain.tld

Hot Tier
Hi
I'm looking for an advise on hot tier feature - how can I tell if the hot
tier is working?
I've attached replicated-distributed hot tier to an EC volume.
Yet, I don't think it's working, at least I don't see any files directly on
the bricks (only folder structure). 'Status' command has all 0s and 'In
progress' for all servers.

Why files goes to hot tier and cold tier at same time
Hi Guys
Got a quick question regarding hot tier and cold tier.
I got a gluster volume with 1 x 3 hot tier and 1 x 3 cold tier.
watermark-low is 75 and watermark-hi is 90. usage of volume is very less.
My files always go to hot tier and cold tier at same time
As I understand, data should go to hot tier only until demoted.
Could someone please shed some light into this?
Thanks in advance.
