https://bugzilla.kernel.org/show_bug.cgi?id=151491 --- Comment #13 from Betacentauri (betacentauri@xxxxxxxx) --- The ARM machine I use has very little free memory. So that fits to your analysis. With your information I could also reproduce it in the xfstests environment with nodelalloc. But only 2 times. I set memory in the virtual machine to 256MB (in config.kvm). Then I mounted the filesystem with nodelalloc and executed this little script several times: #!/bin/bash i=0 while [ $i -lt 10 ]; do dd if=/dev/zero of=./test$i bs=1M count=200 > /dev/null cp test$i testx_$i sync let i=i+1 echo $i done Result was this: root@kvm-xfstests:/media/test# ls -las total 4097028 256 drwxr-xr-x 3 root root 4096 Nov 20 17:43 . 4 drwxr-xr-x 3 root root 4096 Nov 20 17:33 .. 256 -rwxr-xr-x 1 root root 155 Nov 20 17:48 h.sh 256 drwx------ 2 root root 16384 Nov 20 17:26 lost+found 204800 -rw-r--r-- 1 root root 209715200 Nov 20 17:48 test0 205056 -rw-r--r-- 1 root root 209715200 Nov 20 17:48 test1 204800 -rw-r--r-- 1 root root 209715200 Nov 20 17:48 test2 204800 -rw-r--r-- 1 root root 209715200 Nov 20 17:48 test3 204800 -rw-r--r-- 1 root root 209715200 Nov 20 17:48 test4 ... One file has size 205056. But I cannot really reproduce it. So better focus on fixing the bug than on trying to reproduce it with nodelalloc. If I find a way to reproduce, I'll let you know ;-) -- You are receiving this mail because: You are watching the assignee of the bug.
