You can check the state of files on servers with getfattr -d -m. -e hex /path-to-file-on-gluster-server both should return 0x000000000000000000000000 2014-08-08 9:11 GMT+03:00 [email protected] <[email protected]>: Yes, I do not wait for synchronization to complete.

Usually it need 10-15 minutes. Sometimes faster. 2014-08-08 5:19 GMT+03:00 [email protected] <[email protected]>: hi: I have a problem about split-brain, details as below: PC1 and PC2 is AFR, stored a file 1.txt 1. write "123" to 1.txt, then 1.txt in pc1 is same with 1.txt in PC2, content is "123" 2.
