Thanks for the link! I'll spin up a test system with 2.12.0 and see what breaks. -Nate On Fri, Feb 22, 2019 at 12:20 PM Peter Jones wrote: > Nathan > > > > Yes 2.12 is an LTS branch. We’re planning on putting out both 2.10.7 and > 2.12.1 this quarter but have been focusing on the former first to

Re: [lustre-discuss] Suspended jobs and rebooting lustre servers

This is not really correct. Lustre clients can handle the addition of OSTs to a running filesystem. The MGS will register the new OSTs, and the clients will be notified by the MGS that the OSTs have been added, so no need to unmount the clients during this process. Cheers, Andreas On Feb 21,

Nathan Yes 2.12 is an LTS branch. We’re planning on putting out both 2.10.7 and 2.12.1 this quarter but have been focusing on the former first to allow for more time to receive feedback from early adopters on 2.12.0. You can see the patches that will land starting to accumulate here - https://

Re: [lustre-discuss] Which release to use?

Hi Peter, Somewhat related: where should we be looking for the commits leading up to 2.12.1? The b2_12 branch ( https://git.whamcloud.com/?p=fs/lustre-release.git;a=shortlog;h=refs/heads/b2_12) has no activity since 2.12.0 was released. I assumed that if 2.12 is a LTS branch like 2.10, there wou

Re: [lustre-discuss] Which release to use?

2.12.0 is relatively new. It does have some improvements over 2.10.x (notably Data on MDT) but if those are not an immediate requirement then using 2.10.6 would be a proven and more comnservative option. 2.12.51 is an interim development build for 2.13 and should absolutely not be used for produ

Hi all, in the git repository i find v2.10.6, v2.12.0 and v2.12.51. Which version should i compile and use for my productive CentOS 7.6 System? Mit freundlichen Grüßen Bernd Melchers -- Archiv- und Backup-Service | fab-serv...@zedat.fu-berlin.de Freie Universität Berlin | Tel. +49-30-838-55905

Re: [lustre-discuss] EINVAL error when writing to a PFL file (lustre 2.12.0)

Thomas, Yeah, that's possible, though I don't think people are regularly running in to this. FWIW, I think the intention was to allow extension of layouts component by component. An incomplete layout can have components added to it. I can conceive of someone using an incomplete layout to en

Re: [lustre-discuss] EINVAL error when writing to a PFL file (lustre 2.12.0)

Hello Patrick, Thank you for the quick reply. No, I have no particular use-case in mind, I'm just playing around with PFL. If this is currently not properly supported, a quick fix could be to prevent the user from creating such incomplete layouts? Regards, Thomas On 2/22/19 5:33 PM, Patrick

[lustre-discuss] Reminder - Lustre Usage Survey: Input Requested

Re: [lustre-discuss] EINVAL error when writing to a PFL file (lustre 2.12.0)

Thomas, This is expected, but it's also something we'd like to fix - See LU-9341. Basically, append tries to instantiate the layout from 0 to infinity, and it fails because your layout is incomplete (ie doesn't go to infinity). May I ask why you're creating a file with an incomplete layout?

[lustre-discuss] EINVAL error when writing to a PFL file (lustre 2.12.0)

Hello, Is it expected to get an error when appending a PFL file made of 2 regions [0 - 1M] and [1M to 6M] even if writing in this range? I get an error when appending it, even when writting in the very first bytes: [root@vm0]# lfs setstripe  -E 1M -c 1 -E 6M -c 2 /mnt/lustre/m_fou3 [root@v

[lustre-discuss] systemd lnet start script has route config commented out

Good Morning, I'm in the process of setting up a new lustre file system, one that will need to reach some nodes through a set of lnet routers. Adding the routes by hand doesn't work but adding them to the lnet_routes.conf file doesn't get picked up on reboot. I looked at the file and foun
