DongliSi commented on issue vitalif/vitastor#3

Non-capacitors SSD flush journal error( set "immediate_commit" to none)

Hi, This problem still exists in v0.5.13, but now it is "Still waiting to flush journal offset 00418000". Interestingly, this problem always does not appear when I run the following command: fio --name benchmark --filename=/root/fio-tempfile.dat --rw=write --size=1G -bs=4M --ioengine=libaio --fsync=10000 --iodepth=32 --direct=1 --numjobs=16 --runtime=60 --group_reporting But this problem always appears when I run the following command: fio --name benchmark --filename=/root/fio-tempfile.dat --rw=write --size=10G -bs=4M --ioengine=libaio --fsync=10000 --iodepth=32 --direct=1 --numjobs=16 --runtime=600 --group_reporting

Non-capacitors SSD flush journal error( set "immediate_commit" to none)

Hi, I reappear this problem using v0.5.10. This problem is easy to appear under very high io load. Eg: run "fio --name benchmark --filename=/root/fio-tempfile.dat --rw=write --size=1G -bs=4M --ioengine=libaio --fsync=10000 --iodepth=32 --direct=1 --numjobs=16 --runtime=60 --group_reporting" in a Linux virtual machine
