So I re-created the setup to clear things out. This time having mmcsd0s3 partition and mmcsd0s3a in freebsd-ufs type. You can see below sequences of procedures. I deleted the existing mmcsd0s3 partition first and then create a new one in the same 8GB size. root@sd-ultra:~ # /sbin/gpart delete -i 3 mmcsd0 mmcsd0s3 deleted root@sd-ultra:~ # /sbin/gpart show -p => 63 124735425 mmcsd0 MBR (59G) 63 1985 - free - (993K) 2048 102400 mmcsd0s1 fat32lba [active] (50M) 104448 10381312 mmcsd0s2 freebsd (5.0G) 10485760 114249728 - free - (54G) => 0 10381312 mmcsd0s2 BSD (5.0G) 0 128 - free - (64K) 128 10381184 mmcsd0s2a freebsd-ufs (4.9G) root@sd-ultra:~ # /sbin/gpart add -t freebsd -s 8G mmcsd0 mmcsd0s3 added root@sd-ultra:~ # /sbin/gpart show -p => 63 124735425 mmcsd0 MBR (59G) 63 1985 - free - (993K) 2048 102400 mmcsd0s1 fat32lba [active] (50M) 104448 10381312 mmcsd0s2 freebsd (5.0G) 10485760 16777216 mmcsd0s3 freebsd (8.0G) 27262976 97472512 - free - (46G) => 0 10381312 mmcsd0s2 BSD (5.0G) 0 128 - free - (64K) 128 10381184 mmcsd0s2a freebsd-ufs (4.9G) => 0 16777216 mmcsd0s3 BSD (8.0G) 0 16777216 mmcsd0s3a freebsd-ufs (8.0G) => 0 16777216 ufsid/65c95062ec444331 BSD (8.0G) 0 16777216 ufsid/65c95062ec444331a freebsd-ufs (8.0G) root@sd-ultra:~ # root@sd-ultra:~ # /sbin/newfs -U -t /dev/mmcsd0s3a /dev/mmcsd0s3a: 8192.0MB (16777216 sectors) block size 32768, fragment size 4096 using 14 cylinder groups of 625.22MB, 20007 blks, 80128 inodes. with soft updates super-block backups (for fsck_ffs -b #) at: 192, 1280640, 2561088, 3841536, 5121984, 6402432, 7682880, 8963328, 10243776, 11524224, 12804672, 14085120, 15365568, 16646016 root@sd-ultra:~ # root@sd-ultra:~ # /sbin/gpart show -p => 63 124735425 mmcsd0 MBR (59G) 63 1985 - free - (993K) 2048 102400 mmcsd0s1 fat32lba [active] (50M) 104448 10381312 mmcsd0s2 freebsd (5.0G) 10485760 16777216 mmcsd0s3 freebsd (8.0G) 27262976 97472512 - free - (46G) => 0 10381312 mmcsd0s2 BSD (5.0G) 0 128 - free - (64K) 128 10381184 mmcsd0s2a freebsd-ufs (4.9G) => 0 16777216 mmcsd0s3 BSD (8.0G) 0 16777216 mmcsd0s3a freebsd-ufs (8.0G) => 0 16777216 ufsid/65c93f4a5cb247cf BSD (8.0G) 0 16777216 ufsid/65c93f4a5cb247cfa freebsd-ufs (8.0G) root@sd-ultra:~ # root@sd-ultra:~ # mount /dev/mmcsd0s3a /mnt root@sd-ultra:~ # root@sd-ultra:~ # /sbin/gpart show -p => 63 124735425 mmcsd0 MBR (59G) 63 1985 - free - (993K) 2048 102400 mmcsd0s1 fat32lba [active] (50M) 104448 10381312 mmcsd0s2 freebsd (5.0G) 10485760 16777216 mmcsd0s3 freebsd (8.0G) 27262976 97472512 - free - (46G) => 0 10381312 mmcsd0s2 BSD (5.0G) 0 128 - free - (64K) 128 10381184 mmcsd0s2a freebsd-ufs (4.9G) => 0 16777216 mmcsd0s3 BSD (8.0G) 0 16777216 mmcsd0s3a freebsd-ufs (8.0G) root@sd-ultra:~ # cp /home/freebsd/file01 /mnt/file01 root@sd-ultra:~ # cd /mnt root@sd-ultra:/mnt # root@sd-ultra:/mnt # ls -lah total 1421036 drwxr-xr-x 3 root wheel 512B Feb 11 21:44 . drwxr-xr-x 21 root wheel 512B Feb 11 20:04 .. drwxrwxr-x 2 root operator 512B Feb 11 21:42 .snap -rw-r--r-- 1 root wheel 1.4G Feb 11 21:47 file01 root@sd-ultra:/mnt # root@sd-ultra:/mnt # cp file01 file02 root@sd-ultra:/mnt # ls -lah total 2842060 drwxr-xr-x 3 root wheel 512B Feb 11 22:01 . drwxr-xr-x 21 root wheel 512B Feb 11 20:04 .. drwxrwxr-x 2 root operator 512B Feb 11 21:42 .snap -rw-r--r-- 1 root wheel 1.4G Feb 11 21:47 file01 -rw-r--r-- 1 root wheel 1.4G Feb 11 22:03 file02 root@sd-ultra:/mnt # root@sd-ultra:/mnt # rm * root@sd-ultra:/mnt # root@sd-ultra:/mnt # gstat -d dT: 1.003s w: 1.000s L(q) ops/s r/s kBps ms/r w/s kBps ms/w d/s kBps ms/d %busy Name 15 327 15 479 31.0 1 32 7.6 311 1242254 30.9 53.1| mmcsd0 0 0 0 0 0.0 0 0 0.0 0 0 0.0 0.0| mmcsd0s1 0 0 0 0 0.0 0 0 0.0 0 0 0.0 0.0| mmcsd0s2 5 33 15 479 31.0 1 32 7.6 17 1176886 53.3 50.9| mmcsd0s3 0 0 0 0 0.0 0 0 0.0 0 0 0.0 0.0| msdosfs/EFI 0 0 0 0 0.0 0 0 0.0 0 0 0.0 0.0| mmcsd0s2a 5 33 15 479 31.0 1 32 7.6 17 1176886 53.3 50.9| mmcsd0s3a 0 0 0 0 0.0 0 0 0.0 0 0 0.0 0.0| ufs/rootfs The TRIM activity were observed the same as previous but having the mmcsd0s3a along with mmcsd0s3 and mmcsd0.
