While trying to create a file with many components, I ran into a few problems. Firstly, I tried creating a file with no layout, and then adding components to the file in a loop: # mcreate /mnt/testfs/comp
# for C in {1..50}; do lfs setstripe --component-add -E ${C}M -c 1 /mnt/testfs/comp; done
First extent to be set [0, 1048576) isn't adjacent with the existing file extent
end: 18446744073709551615
Create a new file with a specific striping pattern or
set the default striping pattern on an existing directory or
delete the default striping pattern from an existing directory or
add layout component(s) to an existing composite file or
delete specified component(s) from an existing composite file
I think this is a bug, since there is no previous component, and the "end" should be 0 which would allow this to succeed. Then I tried to add only the first component without --component-add, but this also failed even though there is no layout yet: # lfs getstripe /mnt/testfs/comp /mnt/testfs/comp has no stripe info # lfs setstripe --component-add -E 1M -c 1 /mnt/testfs/comp Create composite file /mnt/testfs/comp failed. File exists error: setstripe: create composite file '/mnt/testfs/comp' failed: File exists |
