Topic
Updated nfs-ganesha packages that fix various bugs are now available for Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux 7.
Description
NFS-Ganesha is a user space file server for the NFS protocol with support for NFS v3 and v4.0
The nfs-ganesha packages has been upgraded to upstream version 2.5.5, which provides a number of bug fixes and enhancements over the previous version. (#1472942)
This update adds the following enhancements:
- With this release, xreaddirplus option is now turned on by default. When xreaddirplus option is turned off, NFS falls back to standardreaddir instead of readdirp. Turning xreaddirplus off would result in more lookup and stat requests being sent from the client which may impact performance. (BZ#1489378)
- With Red Hat Gluster Storage 3.4, NFS-Ganesha log files have been moved to the /var/log/ganesha subdirectory. (BZ#1516699)
- NFS-Ganesha-2.5.x allows registration of NFSv3 on UDPv6. (BZ#1517790)
This advisory also fixes the following bugs:
- NFS Ganesha internally uses a different file descriptor for every lock request. When a client removes a file with a specific file descriptor, other clients who are trying to access the same file with the same file descriptor receive “No such file or directory” error. With this fix, lock request uses the same file descriptor obtained from an open call and no additional open call in the lock handling path is required. (BZ#1480138)
- To limit the NFS version to 3 and 4.0, NFSv4 blocks were added in ganesha.conf file manually. With this fix, these options are added as default in ganesha.conf file. (BZ#1514615)
- Currently, the default interval (in microseconds) between upcall polls is 10 microseconds. For large numbers of threads, this results in a lot of CPU consumption. With this fix, the default polling interval has been increased to 100 milliseconds (100000 microseconds) and helps reduce CPU consumption. (BZ#1481040)
- NFS-Ganesha crashed on NFS version 3 request if the GUARDED flag was set to true. The GUARDED flag checks for the presence of a duplicate file before performing the create or open call and should fail the request with NFS3ERR_EXIST if a duplicate file exists. With this fix, the GUARDED flag can handle the NFS version 3 create request and does not crash NFS-Ganesha. (BZ#1520751)
- While exporting/unexporting multiple volumes in a loop, NFS-Ganesha process goes into failed state and then restarts on its own. The export id cache entry is also updated by race. With this fix, while unexporting, refcount on entry is taken into account and the race is closed. (BZ#1577325)
Users of NFS-Ganesha with Red Hat Gluster Storage are advised to update to these packages which fixes these bugs and adds the enhancements.
