Ok, in /boot/loader.conf, I have added the following:
ahci_load="YES"
geom_mbr_load="YES"
msdosfs_iconv_load="YES"
# dmesg | grep ada0
ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
ada0: <ADATA XPG SSD 64GB J090310> ATA-7 SATA 2.x device
ada0: 150.000MB/s transfers (SATA 1.x, UDMA5, PIO 512bytes)
ada0: 61616MB (126189568 512 byte sectors: 16H 63S/T 16383C)
# mount
/dev/ad0s1a on / (ufs, NFS exported, local)
devfs on /dev (devfs, local, multilabel)
procfs on /proc (procfs, local)
tmpfs on /tmp (tmpfs, local)
devfs on /var/named/dev (devfs, local, multilabel)
/dev/ada0s1 on /test1 (ufs, local, soft-updates)
/dev/ada0s2 on /test2 (msdosfs, NFS exported, local)
# gpart show ada0
gpart: No such geom: ada0.
# umount /test1 && umount /test2
# gpart show ada0
=> 63 126189504 ada0 MBR (60G)
63 81919089 1 freebsd [active] (39G)
81919152 44255358 2 !12 (21G)
126174510 15057 - free - (7.4M)
My question is why should I umount /test1 and /test2 then gpart can
show ada0 partition.
Any idea? Thank you very much!
Regards,
Dave.
