We have a setup that requires a lot of tar being used on lustre. We see a
drop in tar performance when going to the lustre setup. I have searched
and found the lustre tar 1.19. Unfortunate this did not provide any
improvement in the tar times. Are there any suggestions for improving tar
with lustre.
tar to extract a 5.2GB file on to the lustre system - 3m22s
tar to extract the same 5.2GB file on to local disk - 1m06s
tat to create a 5.2GB tar file on the lustre system - 4m10s
tar to create the same 5.2GB file on to local disk - 2m21s
Environment
Lustre 1.8.4
4 - OSS servers
2- 2.5TB OST's per OSS
10Gbe Network
Thank you
Rocky
