Unused data on the disk - Error Code 8: Server memory error


#1

Hi, We have a problem

  • Configuration is the same as I posted before in thread
  • Aerospike version now is 3.3.17
  • no anomalies in logs

Aerospike server responds to the client "java.lang.Throwable: com.aerospike.client.AerospikeException: Error Code 8: Server memory error"

Console tells us that we are using 63% of the disk.

Aerospike can not be written to disk because the disk is full. I set “min-avail-pct=0” to namespace, it helped for a while.

What the data filled in the entire disk? What must be done to release the disk of unnecessary data?

Namespace:

namespace ssd {
replication-factor                2
default-ttl                       0
memory-size                       118G
high-water-memory-pct             95
high-water-disk-pct               95
stop-writes-pct                   99
storage-engine device {
    scheduler-mode                noop
    device                        /dev/sda4
    device                        /dev/sdb4
    device                        /dev/sdc4
    device                        /dev/sdd4
    write-block-size              128k
}

Server errors after system disk full

Hi,

After looking at your configuration on the other thread, I can’t find any settings for your defrag-lwm-pct. Can I have you post the actual configuration from Aerospike server and the last 2000 logs?

For Aerospike log:

tail -2000 /var/log/aerospike/aerospike.log

It seems that Aerospike might not be evicting or its defrag is not keeping up. One more thing, I take it your client is handling the ttl? Since I see from your posting above your default-ttl is 0.

You are running with extremely unsafe settings of 99% HWM! You should be running with 50-60% HWM. Also, Your avail pct is on 4% which will hit stop-writes true.

For practical purpose, avail pct is more critical than free disk pct. Also, how much is your memory consumption. Can you post a screenshot of memory as well from the AMC.


#4

Yes default ttl 0, we use our job for cleanup old data.

I add 1 node to cluster. All 5 node on that moment have some configuration

Hi,

Can I know what your defrag-lwm-pct is set to? You can grab that info out of the aerospike.conf. Or if not you can also run the following command : asmonitor -e “asinfo -v “namespace/ssd””

We need to know what your defrag-lwm-pct is set to. Since your defrag is not keeping up with your writes. Also that 20% is un-defraged space, it is not garbage space.

Hi Previously set in "50" We had structural changes, and the entire cluster was restarted. Now is “99”

~ # asmonitor -e “asinfo -v “namespace/ssd””

I would recommend moving your defrag-lwm-pct back to 50. By putting defrag-lwm-pct to that high of a percentage (99) means more blocks to be defragmented, and more dense data on the disk which may lead to latency.

Also is there a reason why your stop writes, high-water-disk-pct and high-water-memory-pct is at 99 pct? Since I believe we recommend the HWM to be around 50-60% & stop-writes to be around 90%.
