Re: [Gluster-users] question about info and info.tmp

Hi Atin, It seems that this workaround should be done by manual. Is that right? And even the files in bricks/* may be empty too. Do you have a workaround, which is implemented in glusterfs code？ Thanks, Xin 在 2016-11-25 15:36:29，"Atin Mukherjee" 写道： On Fri, Nov

Hi Atin, Do you mean that you have the workaround applicable now？ Or it will take time to design the workaround？ If you have workaround now, could you share it to me ? Thanks, Xin, 在 2016-11-24 19:12:07，"Atin Mukherjee" 写道： Xin - I appreciate your patience. I'd

Xin - I appreciate your patience. I'd need some more time to pick this item up from my backlog. I believe we have a workaround applicable here too. On Thu, 24 Nov 2016 at 14:24, songxin wrote: > > > > Hi Atin, > Actually, the glusterfs is used in my project. > And our test

Hi Xin, I've not got a chance to look into it yet. delete stale volume function is in place to take care of wiping off volume configuration data which has been deleted from the cluster. However we need to revisit this code to see if this function is anymore needed given we recently added a

Re: [Gluster-users] question about info and info.tmp

Hi Atin, Thank you for your support. I have a question for you. glusterd_store_volinfo() will hidden remove the info and bricks/* by rename(). Why glusterd must remove the info and bricks/* in function glusterd_delete_stale_volume() before calling glusterd_store_volinfo()? Thanks, Xin

Hi Atin, I think the root cause is in the function glusterd_import_friend_volume as below. int32_t glusterd_import_friend_volume (dict_t *peer_data, size_t count) { ... ret = glusterd_volinfo_find (new_volinfo->volname, _volinfo); if (0 == ret) { (void)

Re: [Gluster-users] question about info and info.tmp

Did you run out of disk space by any chance? AFAIK, the code is like we write new stuffs to .tmp file and rename it back to the original file. In case of a disk space issue I expect both the files to be of non zero size. But having said that I vaguely remember a similar issue (in the form of a bug
