Description of problem: ======================= When tried to delete the files/directories that are in split brain from Fuse and NFS mount, it is successful from fuse but returns input/output error from NFS. From Fuse Client: ================= [f]# rm -rf * [f]# [f]# ls [f]# [f]# pwd /mnt/vol-dis-rep/f [f]# From NFS Client: ================ [n]# ls dir.1 dir.10 dir.2 dir.3 dir.4 dir.5 dir.6 dir.7 dir.8 dir.9 file.1 file.10 file.2 file.3 file.4 file.5 file.6 file.7 file.8 file.9 [n]# [n]# rm -rf * rm: cannot remove `dir.1/file.1': Input/output error rm: cannot remove `dir.1/file.2': Input/output error rm: cannot remove `dir.1/file.3': Input/output error rm: cannot remove `dir.1/file.4': Input/output error rm: cannot remove `dir.1/file.5': Input/output error rm: cannot remove `dir.10/file.2': Input/output error rm: cannot remove `dir.10/file.3': Input/output error rm: cannot remove `dir.10/file.4': Input/output error rm: cannot remove `dir.10/file.5': Input/output error rm: cannot remove `dir.10/file.1': Input/output error rm: cannot remove `dir.2/file.2': Input/output error rm: cannot remove `dir.2/file.3': Input/output error rm: cannot remove `dir.2/file.4': Input/output error rm: cannot remove `dir.2/file.5': Input/output error rm: cannot remove `dir.2/file.1': Input/output error rm: cannot remove `dir.3/file.2': Input/output error rm: cannot remove `dir.3/file.3': Input/output error rm: cannot remove `dir.3/file.4': Input/output error rm: cannot remove `dir.3/file.5': Input/output error rm: cannot remove `dir.3/file.1': Input/output error rm: cannot remove `dir.4/file.1': Input/output error rm: cannot remove `dir.4/file.2': Input/output error rm: cannot remove `dir.4/file.3': Input/output error rm: cannot remove `dir.4/file.4': Input/output error rm: cannot remove `dir.4/file.5': Input/output error rm: cannot remove `dir.5/file.2': Input/output error rm: cannot remove `dir.5/file.3': Input/output error rm: cannot remove `dir.5/file.4': Input/output error rm: cannot remove `dir.5/file.5': Input/output error rm: cannot remove `dir.5/file.1': Input/output error rm: cannot remove `dir.6/file.1': Input/output error rm: cannot remove `dir.6/file.2': Input/output error rm: cannot remove `dir.6/file.3': Input/output error rm: cannot remove `dir.6/file.4': Input/output error rm: cannot remove `dir.6/file.5': Input/output error rm: cannot remove `dir.7/file.1': Input/output error rm: cannot remove `dir.7/file.2': Input/output error rm: cannot remove `dir.7/file.3': Input/output error rm: cannot remove `dir.7/file.4': Input/output error rm: cannot remove `dir.7/file.5': Input/output error rm: cannot remove `dir.8/file.2': Input/output error rm: cannot remove `dir.8/file.3': Input/output error rm: cannot remove `dir.8/file.4': Input/output error rm: cannot remove `dir.8/file.5': Input/output error rm: cannot remove `dir.8/file.1': Input/output error rm: cannot remove `dir.9/file.1': Input/output error rm: cannot remove `dir.9/file.2': Input/output error rm: cannot remove `dir.9/file.3': Input/output error rm: cannot remove `dir.9/file.4': Input/output error rm: cannot remove `dir.9/file.5': Input/output error rm: cannot remove `file.1': Input/output error rm: cannot remove `file.10': Input/output error rm: cannot remove `file.2': Input/output error rm: cannot remove `file.3': Input/output error rm: cannot remove `file.4': Input/output error rm: cannot remove `file.5': Input/output error rm: cannot remove `file.6': Input/output error rm: cannot remove `file.7': Input/output error rm: cannot remove `file.8': Input/output error rm: cannot remove `file.9': Input/output error [n]# pwd /mnt/nvol/n [n]# Version-Release number of selected component (if applicable): ============================================================= [n]# rpm -qa | grep gluster glusterfs-fuse-3.4.0.9rhs-1.el6.x86_64 glusterfs-3.4.0.9rhs-1.el6.x86_64 glusterfs-debuginfo-3.4.0.9rhs-1.el6.x86_64 glusterfs-devel-3.4.0.9rhs-1.el6.x86_64 glusterfs-rdma-3.4.0.9rhs-1.el6.x86_64 [n]# How reproducible: ================= 1/1 Steps Carried: ============== 1. Created 6*2 volume from 4 servers 2. Mounted on Client (NFS and FUSE) 3. Created directory names f and n from fuse mount 4. From fuse mount cd to f 5. From NFS mount cd to n 6. Metadata,data and entry self heal were set to off "for i in {'metadata','data','entry'} ; do gluster volume set <volume_name> $i-self-heal off ; done" 7. From both the mounted directories executed the following command to create directories, files within directories and files: for i in `seq 1 10` ; do mkdir dir.$i ; for j in `seq 1 5` ; do dd if=/dev/urandom of=dir.$i/file.$j bs=1K count=1 ; done ; dd if=/dev/urandom of=file.$i bs=1k count=1 ; done 8. Set the self-heal-daemon to off gluster volume set <vol_name> self-heal-daemon off 9. Brought down all bricks from server 2 and server 4 (kill -9) 10. Modified the content of files from both the mounted directories (f and n) for i in `seq 1 10` ; do for j in `seq 1 5` ; do dd if=/dev/urandom of=dir.$i/file.$j bs=1M count=1 ; done ; dd if=/dev/urandom of=file.$i bs=1k count=1 ; done 10. Brought back the bricks of server 2 and server 4 using "gluster volume start <vol-name> force" 11. Killed the brick processes of server 1 and server 3 which were earlier UP. 12. Modify the content of files from fuse and nfs mounted directories (f and n) for i in `seq 1 10` ; do for j in `seq 1 5` ; do dd if=/dev/urandom of=dir.$i/file.$j bs=1M count=1 ; done ; dd if=/dev/urandom of=file.$i bs=1k count=1 ; done 13. Modification of files should be successful. 14. Remove the files from Fuse and NFS mounted directory. NFS complains input/output error but removal from fuse is successful. Actual results: =============== From Fuse Client: ================= [f]# rm -rf * [f]# [f]# ls [f]# [f]# pwd /mnt/vol-dis-rep/f [f]# From NFS Client: ================ [n]# ls dir.1 dir.10 dir.2 dir.3 dir.4 dir.5 dir.6 dir.7 dir.8 dir.9 file.1 file.10 file.2 file.3 file.4 file.5 file.6 file.7 file.8 file.9 [n]# [n]# rm -rf * rm: cannot remove `dir.1/file.1': Input/output error rm: cannot remove `dir.1/file.2': Input/output error Expected results: ================= Should be consistent between Fuse and NFS protocols
