Jaegeuk, I'm still struggling troubleshooting this issue. However, I failed again to reproduce this bug, I doubt the reason may be my test script and environment(device type/size) is different from yours. (btw, I used pmem as back-end device, and test w/ all fault injection points and w/o write_io/checkpoint fault injection points) Could you please share me your run.sh script? and test command? And I'd like to ask what's your device type and size? Thanks, > . >
