@INCO ok that's far to small to compare it to our setup. Thanks for your help anyways.
@LittleFox thats more comparable ;)
@LittleFox ok thats far to small to compare it to our clusters. Thanks for your information anyway.
@LittleFox how big are these images? A minute is quite short if I look at our timings. Could you tell something about the number of OSDs and the current write rate in IOPS across the pool?
@INCO how many OSDs do you have with how many (write) IOPS?
@INCO how big is your cluster? How full and what is your usecase? If we may ask.
@INCO during the run of fstrim the fs is nearly unusably slow. For example 2 Minutes read time for the 40KB the textfile component of node_exporter needs to read.
@LittleFox the performance with HDDs here was too bad and HDDs to cheap.
Do you see major performance issues during the fstrim run on your VMs? How big is your cluster?
@bonnbike da kommen die Backups drauf.
Hey admin colleagues
1) Do you run CEPH?
2) If so, do you have a SSD backed pool?
3) Do you use this pool for RBD images?
If you've answered all three with yes, do you run fstrim inside these RBD devices? (If yes please leave a comment so we can maybe reach out to you.) If you don't do it for a reason please leave a comment.
@blog_reloaded nope, Telehouse.
Na ihr seid ja lustig^^ :) Natürlich haben wir dann mit Tränen im Auge doch IPv4 Konfiguriert, damit wir auch da sicherstellen können das ihr eure/unsere Services erreichen könnt.
@avanc naja die Telekom hat halt mal wieder eine IP gesperrt obwohl wir uns an ihre Regeln halten und dann hat es ewig gebraucht bis wir wieder entsperrt wurden.
