Like.
BX500 has QLC and it need to flush it's SLC cache to it. And it cannot cache sync writes. Also, RAIDz1 has low IOPS compared to a ZFS mirror and is not good for VM/CTs. QLC and RAIDz1 and BX500 have been discussed on this forum so many times that... -
l.leahu-vladucu reacted to t.lamprecht's post in the thread Cephx Key Migration Procedure and Ceph 19.2 Squid Going EOL Soon with Like.

You have honestly saved me a huge amount of time. I was starting to go in circles with SATA ports, cables and individual drives, while the real issue was much more fundamental. I really appreciate you...

there's your problem. Host exposes the full set of cpu flags to the guest, which means all mitigations applicable to your cpu will apply. in a virtualized environment, mitigations will destroy guest performance- Windows most of all...

The fact that YOU do something doesnt make it a good idea or rationalize it as best practices. Its not a "better" point. its a different point. Yes, you should monitor your environment. A hypervisor's function should not have its operating...

gurubert replied to the thread How are people handling ceph v19 osd fragmentation?.One recommendation is to increase the number of placement groups for pools with many objects. This reduces the size of each PG and makes it easier to place them on OSDs avoiding fragmentation. -
Ssteve999 replied to the thread syslog disappeared.The GUI syslog view does not read /var/log/syslog at all. It streams from the systemd journal (journald), so the file being readable only proves that rsyslog or something similar is still writing the file. That split is exactly what you see when...
