Hello to everyone. I'm trying to mount an ext4 partition on NetBSD. This is the NetBSD version that I'm running right now :
localhost# uname -a NetBSD localhost 9.2 NetBSD 9.2 (GENERIC) #0: Wed May 12 13:15:55 UTC 2021 mkre...@mkrepro.netbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64 The disk that I have previously formatted with the ext4 partition and that I want to mount is : WD, 2500BMV External, 1.05 and it is mapped as sd1 and sd2 : localhost# dmesg | grep 2500 [ 2.435070] sd2 at scsibus2 target 0 lun 0: <WD, 2500BMV External, 1.05> disk fixed [ 3.356209] sd1 at scsibus1 target 0 lun 0: <WD, 2500BMV External, 1.05> disk fixed localhost# gpt show sd1 start size index contents 0 1 PMBR 1 1 Pri GPT header 2 32 Pri GPT table 34 2014 Unused 2048 488394752 1 GPT part - Linux data 488396800 335 Unused 488397135 32 Sec GPT table 488397167 1 Sec GPT header but sd2 is another disk : localhost# gpt show sd2 start size index contents 0 1 PMBR 1 1 Pri GPT header 2 32 Pri GPT table 34 2014 Unused 2048 23437701120 1 GPT part - Windows basic data 23437703168 2015 Unused 23437705183 32 Sec GPT table 23437705215 1 Sec GPT header But let's see what says dmesg : localhost# dmesg | grep sd1 [ 2.385071] sd1 at scsibus1 target 0 lun 0: <Corsair, Force 3 SSD, 0> disk fixed [ 2.395070] sd1: 111 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 234441648 sectors [ 2.435070] sd1: GPT GUID: bd2ec49f-a224-436f-9a09-8c04c5d8b19e [ 2.435070] dk8 at sd1: "fc5905ad-96d4-4161-af65-aab3f4061b1c", 262144 blocks at 64, type: msdos [ 2.435070] dk9 at sd1: "00000000-0000-0000-0000-000000000000", 167373677 blocks at 262208, type: ffs [ 2.435070] autoconfiguration error: sd1: wedge named '00000000-0000-0000-0000-000000000000' already exists, manual intervention required [ 10.114939] boot device: sd1 [ 3.356209] sd1 at scsibus1 target 0 lun 0: <WD, 2500BMV External, 1.05> disk fixed [ 3.356209] sd1: 232 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 488397168 sectors [ 6.716210] sd1: GPT GUID: 96241da9-f011-45a8-a7b0-97aea29d7265 -----> [ 6.716210] dk16 at sd1: "Dati", 488394752 blocks at 2048, type: ext2fs localhost# dmesg | grep sd2 [ 2.435070] sd2 at scsibus2 target 0 lun 0: <WD, 2500BMV External, 1.05> disk fixed [ 2.445070] sd2: 232 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 488397168 sectors [ 2.445070] sd2: GPT GUID: 96241da9-f011-45a8-a7b0-97aea29d7265 ----> [ 2.445070] dk10 at sd2: "Dati", 488394752 blocks at 2048, type: ext2fs [ 6.716210] sd2 at scsibus2 target 0 lun 0: <WD, Elements 25A3, 1021> disk fixed [ 6.726209] sd2: fabricating a geometry [ 6.726209] sd2: 11175 GB, 11444192 cyl, 64 head, 32 sec, 512 bytes/sect x 23437705216 sectors [ 6.736209] sd2: fabricating a geometry [ 6.736209] sd2: GPT GUID: 6f2f762b-3696-48a5-8488-61bd05112e74 [ 6.736209] dk17 at sd2: "Elements", 23437701120 blocks at 2048, type: ntfs It seems that there are two different wench to mount,dk16 and dk10. Let's try to mount both of them : localhost# fuse-ext2 /dev/dk16 /mnt/WD2500BMV -o rw+ localhost# ls /mnt/WD2500BMV nothing. localhost# fuse-ext2 /dev/dk10 /mnt/WD2500BMV -o rw+ localhost# ls /mnt/WD2500BMV nothing. None of them is the working one. -- Mario.
