[Help-bash] What could cause ls and echo return different files?

[Peng Yu]

Hi,

I have a file system on glusterfs (http://www.gluster.org/). The
strange thing is that the following commands can give different files.

$ ls xxx.fastq.gz.*
xxx.fastq.gz.finished  xxx.fastq.gz.stdouterr
$ echo xxx.fastq.gz.*
xxx.fastq.gz.finished xxx.fastq.gz.lockfile xxx.fastq.gz.stdouterr

Even more wired, the exact same commands may give different answers
from time to time. This must be somehow related to glusterfs. But is
there a way at the bash level to show what might be wrong.

$ echo xxx.fastq.gz.*
xxx.fastq.gz.finished xxx.fastq.gz.stdouterr
$ ls xxx.fastq.gz.*
xxx.fastq.gz.finished  xxx.fastq.gz.lockfile  xxx.fastq.gz.stdouterr
$ ls xxx.fastq.gz.*
xxx.fastq.gz.finished  xxx.fastq.gz.lockfile  xxx.fastq.gz.stdouterr
$ ls xxx.fastq.gz.*
xxx.fastq.gz.finished  xxx.fastq.gz.lockfile  xxx.fastq.gz.stdouterr
$ echo xxx.fastq.gz.*
xxx.fastq.gz.finished xxx.fastq.gz.lockfile xxx.fastq.gz.stdouterr
$ echo xxx.fastq.gz.*
xxx.fastq.gz.finished xxx.fastq.gz.lockfile xxx.fastq.gz.stdouterr
$ ls xxx.fastq.gz.*
xxx.fastq.gz.finished  xxx.fastq.gz.stdouterr
