Re: [Gluster-users] df does not show full volume capacity after update to 3.12.4

2018-01-31 Thread Freer, Eva B. 
Amar,

Thanks for your prompt reply. No, I do not plan to fix the code and re-compile. 
I was hoping it could be fixed with setting the shared-brick-count or some 
other option. Since this is a production system, we will wait until a fix is in 
a release.

Thanks,
Eva (865) 574-6894

Hi Freer,

Our analysis is that this issue is caused by https://review.gluster.org/17618. 
Specifically, in 'gd_set_shared_brick_count()' from 
https://review.gluster.org/#/c/17618/9/xlators/mgmt/glusterd/src/glusterd-utils.c.

But even if we fix it today, I don't think we have a release planned 
immediately for shipping this. Are you planning to fix the code and re-compile?

Regards,
Amar

Nithya,

Responding to an earlier question: Before the upgrade, we were at 3.103 on 
these servers, but some of the clients were 3.7.6. From below, does this mean 
that “shared-brick-count” needs to be set to 1 for all bricks.

All of the bricks are on separate xfs partitions composed hardware of RAID 6 
volumes. LVM is not used. The current setting for cluster.min-free-inodes was 
5%. I changed it to 6% per your instructions below. The df output is still the 
same, but I haven’t done the
find /var/lib/glusterd/vols -type f|xargs sed -i -e 's/option 
shared-brick-count [0-9]*/option shared-brick-count 1/g'
Should I go ahead and do this?

Can you check if the values have been changed in the .vol files before you try 
this?

These files will be regenerated every time the volume is changed so changing 
them directly may not be permanent. I was hoping setting the 
cluster.min-free-inodes would have corrected this automatically and helped us 
figure out what was happening as we have not managed to reproduce this issue 
yet.

Nithya,

Responding to an earlier question: Before the upgrade, we were at 3.103 on 
these servers, but some of the clients were 3.7.6. From below, does this mean 
that “shared-brick-count” needs to be set to 1 for all bricks.

All of the bricks are on separate xfs partitions composed hardware of RAID 6 
volumes. LVM is not used. The current setting for cluster.min-free-inodes was 
5%. I changed it to 6% per your instructions below. The df output is still the 
same, but I haven’t done the
find /var/lib/glusterd/vols -type f|xargs sed -i -e 's/option 
shared-brick-count [0-9]*/option shared-brick-count 1/g'
Should I go ahead and do this?

Output of stat –f for all the bricks:

Are all of these bricks on separate Filesystem partitions? If yes, can you 
please try running the following on one of the gluster nodes and see if the df 
output works post that?

gluster v set dataeng cluster.min-free-inodes 6%


If it doesn;t work, please send us the stat -f output for each brick.

Sam,

For du –sh on my newer volume, the result is 161T. The sum of the Used space in 
the df –h output for all the bricks is ~163T. Close enough for me to believe 
everything is there. The total for used space in the df –h of the mountpoint it 
83T, roughly half what is used.

Relevant lines from df –h on server-A:
Filesystem  Size  Used Avail Use% Mounted on
/dev/sda159T   42T   17T  72% /bricks/data_A1
/dev/sdb159T   45T   14T  77% /bricks/data_A2
/dev/sdd159T   39M   59T   1% /bricks/data_A4
/dev/sdc159T  1.9T   57T   4% /bricks/data_A3
server-A:/dataeng   350T   83T  268T  24% /dataeng

And on server-B:
Filesystem Size  Used Avail Use% Mounted on
/dev/sdb1   59T   34T   25T  58% /bricks/data_B2
/dev/sdc1   59T  2.0T   57T   4% /bricks/data_B3

We noticed something similar.

Out of interest, does du -sh . show the same size?

We have 2 different server configurations.

bricks, again with 1 on each server. The output of ‘df’ now shows 350TB, but 
the aggregate of 8 – 59TB bricks should be ~466TB.

Configuration 2: A distributed, replicated volume with 9 bricks on each server 
for a total of ~350TB of storage. After the server update to RHEL 6.9 and 
gluster 3.12.4, the volume now shows as having 50TB with ‘df’. No changes were 
made to this volume after the update.

In both cases, examining the bricks shows that the space and files are still 
there, just not reported correctly with ‘df’. All machines have been rebooted 
and the problem persists.

Any help/advice you can give on this would be greatly appreciated.

Thanks in advance.

[Gluster-users] Replace corrupted brick

2015-09-22 Thread Freer, Eva B. 
Our configuration is a distributed, replicated volume with 7 pairs of bricks on 
2 servers. We are in the process of adding additional storage for another brick 
pair. I placed the new disks in one of the servers late last week and used the 
LSI storcli command to make a RAID 6 volume of the new disks. We are running 
RedHat 6.6 and Gluster 3.7.1 on both servers. Yesterday, I ran 'parted 
/dev/sdj' to create a partition on the new volume. Unfortunately, /dev/sdj was 
not the new volume (which is /dev/sdh). I realized the error right away, but 
the system was operating OK and it was late at night so I decided to wait until 
today to try to fix this. This morning, I ran 'parted rescue 0 36.0TB'. This 
runs, but does not find a partition to restore. I am using LVM, and the 
partition is /dev/mapper/vg_data5-lv_data5 with an xfs filesystem on it. The 
system continued to operate, but I expected that there would be problems on 
re-boot. I re-booted and indeed, the system can't find the volume at 
/dev/mapper/vg_data5-lv_data5. Is it possible to recover this volume in place, 
or do I need to just drop it from the gluster volume, recreate the lvm 
partition, and then copy the files from its partner brick on the other server? 
If I need to copy the files, what is the best procedure for doing it?

TIA,

Update: I was able to use the TestDisk program from cgsecurity.org to find and 
rewrite the partition info for the LVM partition. I was then able to mount the 
disk and restart the gluster volume to bring the brick back online. To make 
sure everything was OK, I then rebooted the node with the problem. I also 
rebooted all the client nodes so they have a nice clean start for the morning.
