Description david.spisla 2020-02-28 13:48:41 UTC

Description of problem:
If worm-file-level enabled and auto-commit-period 0 an initial write
of a file (e.g. $ echo test >> file1.txt) would lead to an zero byte
file because the WORM xlator immediately WORMed the file when it was
created.


Version-Release number of selected component (if applicable):
5.5

How reproducible:
Steps to Reproduce:
1. Enable worm-file-level for a volume and set auto-commit-period to 0
2. Mount the volume e.g. FUSE, NFS or SMB
3. Write a file e.g. $ echo test >> file1.txt or copy some file to the mountpoint

Actual results:
File will have O Byte and it is WORMed


Expected results:
The new file respective copy should be complete and it is WORMed
(one can check the comleteness with a md5 checksum of the original and new copy)
