1.88.7.1.5. Filesystem and Storage Management Updates
1.88.7.1.5.1. NFS-specific Updates
• Fix a deadlock in the sunrpc code.
BZ#548846
954
• Ensure
dprintk()
macro works everywhere.
BZ#532701
955
• Fix stale
nfs_fattr
being passed to
nfs_readdir_lookup()
BZ#531016
956
• Update
nfs4_do_open_expired()
to prevent infinite loops.
BZ#526888
957
A problem was found with
nfs4_do_open_expired()
that could lead to the reclaimer thread
going into an infinite loop. This bug was triggered when the client received an NFS4ERR_DELAY
from the server, and the exception.retry bit was set, enforcing a timeout. This bit was never reset to
zero (0) when the server recovered, leading to an infinite loop.
This update checks for server recovery and resets the exception.retry bit when appropriate,
preventing the creation of this infinite loop.
• nfsnobody == 4294967294 causes idmapd to stop responding
BZ#519184
958
• statfs on NFS partition always returns 0
BZ#519112
959
A problem was found where
statfs
on NFS partitions always returned a zero (0) value, regardless
of success or fail. On fail,
statfs
should return a negative number.
This update corrects the problem so that
statfs
behaves as expected.
• Read/Write NFS I/O performance was severely degraded by NFS synchronous write RPCs
(FILE_SYNC) that occur when an application has a file open O_RDWR and is reading dirty
pages. This read() system call triggered a flush of the dirty page to the server, using a 4096-byte
synchronous write. The remote filesystem is mounted with an explicit async mount option, and the
application does not open the file with O_SYNC or O_DSYNC flags.
• Mounting with a rsize/wsize of 2048 (less than the 4096 page size) eliminates these synchronous
writes, and dramatically improves I/O.
