similar to: Gluster Server upgrade from 3.5 to 3.8 in online upgrade mode

Thanks for your reply. So the way I understand is that it can be upgraded but with a downtime, which means that there are no clients writing to this gluster volume, as the volume is stopped. But post a upgrade we will still have the data on the gluster volume that we had before the upgrade(but with downtime). - Hemant On 9/13/17 2:33 PM, Diego Remolina wrote: > Nope, not gonna work... I

Nope, not gonna work... I could never go even from 3.6. to 3.7 without downtime cause of the settings change, see: http://lists.gluster.org/pipermail/gluster-users.old/2015-September/023470.html Even when changing options in the older 3.6.x I had installed, my new 3.7.x server would not connect, so had to pretty much stop gluster in all servers, update to 3.7.x offline, then start gluster and

Folks, We have a 12 node replicated gluster with 2 X 6. I need to change IP address in 6 nodes out of the 12 nodes, keeping the host name same. The 6 nodes that I plan to change IP are part of the 3 sub-volumes. Is this possible and if so is there any formal process to tell that there is a change in IP address. My requirement is to keep the volume up and not bring it down. I can change IP

Sending again. Can somebody please take a look and let me know is this is doable? Folks, We have glusters with version 3.8.13 and we are using that for RMAN backups. We get errors/warnings, RMAN-03009: failure of backup command on C1 channel at 03/28/2018 16:55:43 ORA-19510: failed to set size of 184820 blocks for file

Thanks Atin. Peer probes were done using FQDN and I was able to make these changes. The only thing I had to do on rest of the nodes was to flush nscd; after that everything was good and I did not have to restart gluster services on these rest of the nodes. - Hemant On 10/30/17 11:46 AM, Atin Mukherjee wrote: If the gluster nodes are peer probed through FQDNs then you?re good.

If the gluster nodes are peer probed through FQDNs then you?re good. If they?re done through IPs then for every node you?d need to replace the old IP with new IP for all the files in /var/lib/glusterd along with renaming the filenames with have the associated old IP and restart all gluster services. I used to have a script for this which I shared earlier in users ML, need to dig through my mailbox

Hi Diego, Just to clarify, so did you do an offline upgrade with an existing cluster (3.6.x => 3.10.x)? Thanks.

Yes, I did an offline upgrade. 1. Stop all clients using gluster servers. 2. Stop glusterfsd and glusterd on both servers. 3. Backed up /var/lib/gluster* in all servers just to be safe. 4. Upgraded all servers from 3.6.x to 3.10.x (I did not have quotas or anything that required special steps) 5. Started gluster daemons again and confirmed everything was fine prior to letting clients connect. 5.

Folks, Currently we have the archive log files from a Oracle DB been written to a nas location using NFS. We are planning to move the nas location use glusterfs file system. Has anybody been able to write archive log files of a Oracle DB onto a glusterfs file system/mount point. If not done then do you all think that this can be done? I am planning to perform some testing and wanted to have

This might be a little late but I was engaged in my university examinations. Moreover, I have an exam even today so apologies for the delay. Also, I had to change my project from weighting schemes to improve to improve estimated total number of results as weighting schemes was demanding a lot of time going through it. I would really appreciate if you could review my proposal asap.

Hi, thanks for suggesions. Yes "gluster peer probe node3? will be first command in order to discover 3rd node by Gluster. I am running on latest 3.7.x - there is 3.7.6-1ubuntu1 installed and latest 3.7.x according https://packages.ubuntu.com/xenial/glusterfs-server <https://packages.ubuntu.com/xenial/glusterfs-server> is 3.7.6-1ubuntu1, so this should be OK. > If you are *not* on

Greetings, I am Hemant Kumar Singh, a computer science undergrad studying in NIT Warangal, India. I am interested to work on the project "Weighting Schemes" under the guidance of Olly Bets and Gaurav Arora; this project requires basic(or better) C++ knowledge and I've done 2 years of basic C++ in my high school. Moreover, this is my 2nd semester pursuing a computer science major in

Thanks, as per my knowledge, after downloading the source code, and making changes and then making sure it works properly , recompiling it and then patch it and finally submit a pull request. But what all changes should I/can I make? Please provide me some insight into this. Thanks&Regards, Hemant Kumar Singh On Apr 10 2019, at 10:56 am, Gaurav Arora <gauravarora.daiict at gmail.com>

Okay thanks, how do I make a patch and submit one? Do you have a link for the same?

Following is the output of top command at my server and i find the high usage very much alarming. We are basically a team of three developers working on same machine(remotely), so we run mongrel_rails servers from out ~/public/app directories. We also run a cluster of mongrel servers using apache2.2. Is this much memory use normal? PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+

Hello Ulrik, Can you please explain this code means how and what this code is doing because I'm not able to understand it, if you can explain it i can use it in future by doing some Lil bit manipulation. Thanks data_help <- data_help %>% mutate(Purchase_ID = 1:n()) %>% group_by(Purchase_ID) %>% do(split_items(.)) cat_help %>% gather("Foo",

Well it was probably caused by running replica 2 and doing online upgrade. However I added brick, turned volume to replica 3 with arbiter and got very strange issue I will mail to this list in a moment...

Hi Hemant, the solution is really quite similar, and the logic is identical: library(readr) library(dplyr) library(stringr) library(tidyr) data_help <- read_csv("data_help.csv") cat_help <- read_csv("cat_help.csv") # Helper function to split the Items and create a data_frame split_items <- function(items){ x <- items$Items_purchased_on_Receipts %>%
