Hi Pranith,if I restart glusterd service in the node alone will it work. bcoz I feel that doing volume force start will trigger bitrot process to crawl disks in all nodes.
Have you enabled bitrot? If not then the process will not be in existence. As a workaround you can always disable this option before executing volume start force. Please note volume start force doesn't affect any running processes.
yes, rebalance fix layout is on process.regardsAmudhanOn Tue, Apr 25, 2017 at 9:15 PM, Pranith Kumar Karampuri <pkarampu@xxxxxxxxxx> wrote:You can restart the process using:gluster volume start <volname> force
Did shd on this node heal a lot of data? Based on the kind of memory usage it showed, seems like there is a leak.Sunil,Could you find if there any leaks in this particular version that we might have missed in our testing?On Tue, Apr 25, 2017 at 8:37 PM, Amudhan P <amudhan83@xxxxxxxxx> wrote:______________________________Hi,In one of my node glustershd process is killed due to OOM and this happened only in one node out of 40 node cluster.Node running on Ubuntu 16.04.2.dmesg output:[Mon Apr 24 17:21:38 2017] nrpe invoked oom-killer: gfp_mask=0x26000c0, order=2, oom_score_adj=0[Mon Apr 24 17:21:38 2017] nrpe cpuset=/ mems_allowed=0[Mon Apr 24 17:21:38 2017] CPU: 0 PID: 12626 Comm: nrpe Not tainted 4.4.0-62-generic #83-Ubuntu[Mon Apr 24 17:21:38 2017] 0000000000000286 00000000fc26b170 ffff88048bf27af0 ffffffff813f7c63[Mon Apr 24 17:21:38 2017] ffff88048bf27cc8 ffff88082a663c00 ffff88048bf27b60 ffffffff8120ad4e[Mon Apr 24 17:21:38 2017] ffff88087781a870 ffff88087781a860 ffffea0011285a80 0000000100000001[Mon Apr 24 17:21:38 2017] Call Trace:[Mon Apr 24 17:21:38 2017] [<ffffffff813f7c63>] dump_stack+0x63/0x90[Mon Apr 24 17:21:38 2017] [<ffffffff8120ad4e>] dump_header+0x5a/0x1c5[Mon Apr 24 17:21:38 2017] [<ffffffff811926c2>] oom_kill_process+0x202/0x3c0[Mon Apr 24 17:21:38 2017] [<ffffffff81192ae9>] out_of_memory+0x219/0x460[Mon Apr 24 17:21:38 2017] [<ffffffff81198a5d>] __alloc_pages_slowpath.constprop.88+0x8fd/0xa70 [Mon Apr 24 17:21:38 2017] [<ffffffff81198e56>] __alloc_pages_nodemask+0x286/0x2a0 [Mon Apr 24 17:21:38 2017] [<ffffffff81198f0b>] alloc_kmem_pages_node+0x4b/0xc0 [Mon Apr 24 17:21:38 2017] [<ffffffff8107ea5e>] copy_process+0x1be/0x1b70[Mon Apr 24 17:21:38 2017] [<ffffffff8122d013>] ? __fd_install+0x33/0xe0[Mon Apr 24 17:21:38 2017] [<ffffffff81713d01>] ? release_sock+0x111/0x160[Mon Apr 24 17:21:38 2017] [<ffffffff810805a0>] _do_fork+0x80/0x360[Mon Apr 24 17:21:38 2017] [<ffffffff8122429c>] ?
