"gluster volume info" and "gluster vol status" would help in us debug faster. However, coming to gfid mismatch, yes the file "abbreviations.log" (I assume the other brick copy also to be " abbreviations.log" and not "breviations.log" ....typo mistake?) is in gfid mismatch leading to IO error(gfid splitbrain) Resolving data and metadata splitbrains are not recommended to be done from backend brick. But in case of a GFID splitbrain(like in file abbreviations.log), the only method available is resolving from backend brick You can read more about this in http://gluster.readthedocs.io/en/latest/Troubleshooting/split-brain/?highlight=gfid (Fixing Directory entry split-brain section) (There is a bug already existing to resolve gfid splitbrain using CLI ) thanks, nagpavan ----- Original Message ----- From: "lejeczek" <peljasz@xxxxxxxxxxx> To: "Nag Pavan Chilakam" <nchilaka@xxxxxxxxxx> Cc: gluster-users@xxxxxxxxxxx Sent: Tuesday, 7 February, 2017 10:53:07 PM Subject: Re: Input/output error - would not heal On 07/02/17 12:50, Nag Pavan Chilakam wrote: > Hi, > Can you help us with more information on the volume, like volume status and volume info > One reason of "transport endpoint error" is the brick could be down > > Also, i see that the syntax used for healing is wrong. > You need to use as below: > gluster v heal <vname> split-brain source-brick <brick path> <filename considering brick path as /> > > In yourcase if brick path is "/G-store/1" and the file to be healed is "that_file" , then use below syntax (in this case i am considering "that_file" lying under the brick path directly" > > gluster volume heal USER-HOME split-brain source-brick 10.5.6.100:/G-store/1 /that_file that was that, my copy-paste typo, it does not heal.
