Question

我正在使用pgbench进行性能测试，以评估使用Glusterfs和Postgresql的影响。我用3块砖/服务器创建了一个gluster复制卷：

Volume Name: gv0
Type: Replicate
Volume ID: a7e617ec-c564-4a01-aec9-807e87fcccb3
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x 3 = 3
Transport-type: tcp
Bricks:
Brick1: 10.112.76.37:/export/sdb1/brick
Brick2: 10.112.76.38:/export/sdb1/brick
Brick3: 10.112.76.39:/export/sdb1/brick
Options Reconfigured:
transport.address-family: inet
nfs.disable: on
performance.client-io-threads: off

之后我配置了postgres来使用音量gv0。在低压力下一切正常。但是，当负载增加时，会发生以下错误：

client 14 aborted in state 9: ERROR:  unexpected data beyond EOF in block 0 of relation base/16384/16503
HINT:  This has been seen to occur with buggy kernels; consider updating your system.
client 7 aborted in state 9: ERROR:  unexpected data beyond EOF in block 0 of relation base/16384/16503

client 0 aborted in state 9: ERROR:  unexpected data beyond EOF in block 0 of relation base/16384/16503

client 11 aborted in state 9: ERROR:  unexpected data beyond EOF in block 0 of relation base/16384/16503
HINT:  This has been seen to occur with buggy kernels; consider updating your system.

知道造成这种情况的原因是什么？

可能是GlusterFS中的错误

版本4.13之前的内核也存在在fsync（）期间检测错误的问题，并且PostgreSQL在最新版本https://www.percona.com/blog/2019/02/22/postgresql-fsync-failure-fixed-minor-versions-released-feb-14-2019/中应用了相应的更改

因此，有必要在最新版本的Kernel，GlusterFS和PostgreSQL上重新检查此问题。
