[Gluster-users] gluster 5.3: file or directory not read-/writeable, although it exists - cache?

[Hu Bert]

Hello @ll,

one of our backend developers told me that, in the tomcat logs, he
sees errors that directories on a glusterfs mount aren't readable.
Within tomcat the errors look like this:

2019-02-19 07:39:27,124 WARN  Path
/data/repository/shared/public/staticmap/370/626 is existed but it is
not directory
java.nio.file.FileAlreadyExistsException:
/data/repository/shared/public/staticmap/370/626

But the basic directory does exist, has been created on 2019-02-18
(and is readable on other clients):

ls -lah /data/repository/shared/public/staticmap/370/626/

gluster v5.3, debian stretch.
gluster volume info: https://pastebin.com/UBVWSUex
gluster volume status: https://pastebin.com/3guxFq5m

mount options on client:
gluster1:/workdata /data/repository/shared/public glusterfs
defaults,_netdev,lru-limit=0,backup-volfile-servers=gluster2:gluster3
0 0

brick mount options:
/dev/md/4  /gluster/md4  xfs  inode64,noatime,nodiratime  0 0

Hmm... problem with mount options? Or is some cache involved?


Best regards,
Hubert
