I made clean install of 11.4-RELEASE amd64 with ZFS root and UEFI boot mode. 'Auto (ZFS)' was used at disk setup phase and disk was partitioned as following.
---------------------------------------------------------------------- root@rolling-vm-freebsd3[80]# uname -a FreeBSD rolling-vm-freebsd3.home.utahime.org 11.4-RELEASE-p3 FreeBSD 11.4-RELEASE-p3 #0: Tue Sep 1 08:22:33 UTC 2020 r...@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 root@rolling-vm-freebsd3[81]# gpart show ada0 => 40 209715120 ada0 GPT (100G) 40 409600 1 efi (200M) 409640 2008 - free - (1.0M) 411648 16777216 2 freebsd-swap (8.0G) 17188864 192524288 3 freebsd-zfs (92G) 209713152 2008 - free - (1.0M) ---------------------------------------------------------------------- According to it the size of EFI system partition is 200MB. But if I mount it to filesystem and check its size with df(1), then it is much smaller than 200MB. ---------------------------------------------------------------------- root@rolling-vm-freebsd3[82]# mount -t msdosfs /dev/ada0p1 /mnt root@rolling-vm-freebsd3[83]# df -k /mnt Filesystem 1024-blocks Used Avail Capacity Mounted on /dev/ada0p1 779 384 395 49% /mnt ---------------------------------------------------------------------- And if I try to copy large file to /mnt then it fails. ---------------------------------------------------------------------- root@rolling-vm-freebsd3[94]# ls -l dummy.1MB.date -rw-r--r-- 1 root wheel 1048576 Nov 29 10:39 dummy.1MB.date root@rolling-vm-freebsd3[95]# cp dummy.1MB.date /mnt cp: /mnt/dummy.1MB.date: No space left on device ---------------------------------------------------------------------- So it seems kernel(?) really regards the size of mounted EFI system part as only 779KB. I also tried it with 12.2-RELEASE and df(1) reported correctly. ---------------------------------------------------------------------- root@eastasia[1002]# uname -a FreeBSD eastasia.home.utahime.org 12.2-RELEASE FreeBSD 12.2-RELEASE r366954 GENERIC amd64 root@eastasia[1003]# gpart show ada0 => 40 1953525088 ada0 GPT (932G) 40 409600 1 efi (200M) 409640 2008 - free - (1.0M) 411648 16777216 2 freebsd-swap (8.0G) 17188864 1936334848 3 freebsd-zfs (923G) 1953523712 1416 - free - (708K) root@eastasia[1004]# mount -t msdosfs /dev/ada0p1 /mnt root@eastasia[1005]# df -k /mnt Filesystem 1024-blocks Used Avail Capacity Mounted on /dev/ada0p1 204696 976 203720 0% /mnt ---------------------------------------------------------------------- Is there any bug fix about it that is merged to 12.x but not 11.x?
