<div dir="ltr">There are 2 things happen after a reboot.<div><br></div><div>1. glusterd (management layer) does a sanity check of its volumes, and sees if there are anything different while it went down, and tries to correct its state.</div><div> - This is fine as long as number of volumes are less, or numbers of nodes are less. (less is referred as < 100).</div><div><br></div><div>2. If it is a replicate or disperse volume, then self-heal daemon does check if there are any self-heal pending.</div><div> - This does a 'index' crawl to check which files actually changed when one of the brick/node was down.</div><div> - If this list is big, it can sometimes does take some time.</div><div><br></div><div>But 'Days/weeks/month' is not a expected/observed behavior. Is there any logs in the log file? If not, can you do a 'strace -f' to the pid which is consuming major CPU?? (strace for 1 mins sample is good enough).</div><div><br></div><div>-Amar</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Mar 20, 2019 at 2:05 AM Alvin Starr <<a href="mailto:alvin@netvel.net">alvin@netvel.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">We have a simple replicated volume with 1 brick on each node of 17TB.<br>
<br>
There is something like 35M files and directories on the volume.<br>
<br>
One of the servers rebooted and is now "doing something".<br>
<br>
It kind of looks like its doing some kind of sality check with the node <br>
that did not reboot but its hard to say and it looks like it may run for <br>
hours/days/months....<br>
<br>
Will Gluster take a long time with Lots of little files to resync?<br>
