Hi, here http://forum.proxmox.com/threads/14...cs-second-dropped-to-the-ground-what-to-check
is the thread where I learned that my IBM serveraid BBU was to be replaced, which caused automatic Writethrough, and so fsyncs/second drop...

Now, I finally got a replaced battery, that is actually charging, but fsyncs/second are still the same, so I checked more, with:
Code:
megacli -AdpBbuCmd  -aAll

BBU status for Adapter: 0

BatteryType: iBBU
Voltage: 4063 mV
Current: 95 mA
Temperature: 28 C

BBU Properties for Adapter: 0

  Auto Learn Period: 30 Days
  Next Learn time: Jan 1 200 00:00:00
  Learn Delay Interval:0 Hours
  Auto-Learn Mode: Enabled

Exit Code: 0x00

then I tried to force a BBU learn, but it fails:
Code:
  megacli -AdpBbuCmd -BbuLearn -a0

Adapter 0: BBU Learn Failed

Exit Code: 0x01

Now, anyone has experience with this? Is this normal? Will it work when charge is complete?

Or there could be other issues and how to check them?

Thanks, Marco

Yes, I guess it will work as soon as charge is complete.

Well, the command
Code:
megacli -AdpBbuCmd -BbuLearn -a0

worked after full charge, but fsyncs were still low (around 70!)

then i did search more, and found what a "learn cycle" really is:
http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5078572

<<
Step 1: Begin calibration. The controller charges the BBU to maximum capacity.
Step 2: The controller discharges the BBU.
Step 3: The controller recharges the BBU. When maximum capacity is reached, the process is finished.
>>

so it had to again fully discharge and then fully recharge... (it took a while, a few hours...)

and now fsyncs are back to around 3200...

now the only doubt is that issung:
Code:
megacli -AdpBbuCmd  -aAll

as is visible, it says:
"Battery State : Non Operational"
and
"Learn Cycle Requested : Yes"

and I really dont' know why, and what to do more...

any hints, anyone?

well, it took some time to figure out, but it just needed a reboot,
