Yes! A basic
ls only has to contact the meta-data server (MDS), not the object-storage servers (OSS), where the bottleneck often occurs. In general,
ls is aliased to give additional information, which requires the OSS's. You can bypass this by using
/bin/ls. When there are many files in the same directory, and you don't need the output to be sorted,
/bin/ls -U is even faster.
You can also use the Lustre utility
lfs to look for files. For example, the syntax to emulate a regular
ls in any directory is
lfs find -D 0 *
For convenience, you may want to add an alias definition to your login config files. For example Bash users can add to their
~/.bashrc the following line to create an alias called
alias lls="/bin/ls -U"
