Description Martin Birgmeier 2019-12-15 09:03:11 UTC
- FreeBSD 12.1
- All ports recompiled for 12.1
- Using a combination of tar cf - ... | ( cd <exfat-fs> ; tar xfp - ) to copy files to an exfat-formatted SD card

- Since a few weeks, the receiving tar gives messages like

x <filename>: Can't restore time

- I believe this started to happen when I installed FreeBSD 12.1 and recompiled all ports
- The file contents are otherwise o.k. (verified using diff -r)

Scenario (continued):
- I have written a small utility "cptimes" which copies the atime and mtime from one file to another

- Trying to use this utility to correct these times manually results in

[1]% cptimes <sourcefile> <destinationfile>
<destinationfile>: Operation not permitted

One more note: The same commands on another SD-card which is formatted as NTFS and uses sysutils/fusefs-ntfs work fine.

Unable to reproduce and issue is most likely related to the damaged fs on the target sd card.

# mdconfig -a -s 1g

Below is a test provided by me:

# mount.exfat /dev/md0 /mnt/
FUSE exfat 1.3.0

[root@bunny /mnt]# echo test > test
[root@bunny /mnt]# ls -l
total 32
-rwxrwxrwx  1 root  wheel  5 May  3 22:43 test

# rsync -a /etc/hosts /mnt/hosts

# ls -l /mnt/hosts
-rwxrwxrwx  1 root  wheel  1116 Nov 28 14:36 /mnt/hosts

# touch -d "2018-01-02T22:13:14" /mnt/hosts

# stat /mnt/hosts
18446744073391374205 4 -rwxrwxrwx 1 root wheel 0 1116 "Jan  2 22:13:14 2018" "Jan  2 22:13:14 2018" "Jan  2 22:13:14 2018" "Jan  1 00:59:59 1970" 4096 64 0 /mnt/hosts

Also i tested that timestamp persist after remount. My recommendation would be to reformat the card and start from scratch. Feel free to reopen if needed.

O.k. thank you for checking.
