Hi, AIX's implementation of posix_fallocate is a little bit, let me say, peculiar. Attached is a patch to "fix" (=work around) this. Without you'll see this in the logs: Jul 28 01:17:41 trevi mail:err|error dovecot: IMAP(beckerr): posix_fallocate() failed: File exists Jul 28 01:17:41 trevi mail:err|error dovecot: IMAP(beckerr): file_set_size() failed with mbox file

...1322 return -1; When posix_fallocate extends the mailbox beyond the requested 'file_size', a variable size block of NUL bytes is left behind at the tail of the mailbox, with the side effects described above. I successfully worked around this issue by undefining HAVE_POSIX_FALLOCATE, as the performance penalty with falling back to direct block appends seems small. At least a size check (and possible truncation) after the mbox_sync_file_updated call above should probably be added. I thought that the issue would be anyway worth bringing to your attention. Thanks. Francesco Pr...

When I use the preallocate patch and create a 77GB file using the function I get a CPU spike on the server-side. The spike lasts about 20 minutes and uses about 20%-25% of the cpu associated with the rsync instance creating the file. The spike is directly linked to the time it takes to create the file. I compiled rsync using cygwin CVS. I initially suspected the implementation of

A lot of code runs 'qemu-img create' or 'truncate' to create blank disk images. In the past I resisted adding an API to do this, since it essentially duplicates what you can already do using other tools (ie. qemu-img). However this does simplify calling code quite a lot since qemu-img is somewhat error-prone to use (eg: don't try to create a disk called "foo:bar")

Samba 4.12.1, single server with AD+DC on Ubuntu 18.04. Filesystem: /dev/sdb1 on /home type ext4 (rw,relatime,stripe=32750,data=ordered) It all work as expected, but I occasionally get the error in subject which denies access to shares. Restarting Samba will restore functionality. What can be the cause of this problem? Thanks. [2020/05/27 18:24:35.795379, 8]
