Re: NFS mounted but shows nothing even df -h has it
Fixed, thanks Otto. I checked this drive and found an error of "BAD SUPER BLOCK: MAGIC NUMBER WRONG", it's fixed in the end. So I changed the last option of the fstab file from ZERO to TWO thus the command fsck can check it automatically. Thank you all for the great help, I am so happy my little NAS works again. The OpenBSD community is so helpful and there are so many nice people here, hopefully I can serve you all a cup of the tea I made from the mountain, actually I am making tea today. > $ doas fsck -v -t ffs sd0i start sd0i wait fsck_ffs sd0i ** /dev/sd0i (sd0i) BAD SUPER BLOCK: MAGIC NUMBER WRONG LOOK FOR ALTERNATE SUPERBLOCKS?

Re: NFS mounted but shows nothing even df -h has it
Thanks for all the help. Hereby is the result of command `disklabel sd0`, seems the drive is well detected by failed mounted: > $ doas disklabel sd0 # /dev/rsd0c: type: SCSI disk: SCSI disk label: SAMSANG ST1000LM duid: 2b6c2b5b929f9a55 16 partitions: #size offset fstype [fsize bsize cpg] c: 19535251680 unused i: 1758185664 64 4.2BSD 8192 65536 52270 # /mnt/hdd On Wed, May 31, 2023 at 7:56 PM Otto Moerbeek wrote: > > On Wed, May 31, 2023 at 11:21:15AM +0100, Zé Loff wrote: > > > On Wed, May 31, 2023 at 05:25:07PM +0800, Jazzi Hong wrote: > > > You made the point, thank you Maksim. > > > I checked /mnt/hdd and nothing there. > > > > # cat /etc/fstab > > > 1593ab2ee369c420.b none swap sw > > > 1593ab2ee369c420.a / ffs rw 1 1 > > > 1593ab2ee369c420.e /var ffs rw,nodev,nosuid 1 2 > > > 2b6c2b5b929f9a55.i /mnt/hdd ffs rw,noexec,nosuid,nodev 0 0 > > > > # doas sysctl hw.disknames > > > hw.disknames=sd0:2b6c2b5b929f9a55,sd1:1593ab2ee369c420 > > > > # doas fdisk sd0 > > > Disk: sd0 geometry: 121601/255/63 [1953525168 Sectors] > > > Offset: 0 Signature: 0xAA55 > > > Starting Ending LBA Info: > > > #: id C H S - C H S [ start:size ] > > > --- > > > 0: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused > > > 1: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused > > > 2: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused > > > *3: A6 0 1 2 - 121601 80 63 [ 64: 1953525104 ] > > > OpenBSD > > > > > > So /dev/sd0 is my NFS share hard disk, and when I tried to mount it > > > manually: > > > > # doas mount /mnt/hdd > > > mount_ffs: 2b6c2b5b929f9a55.i on /mnt/hdd: Invalid argument > > > +++ > > > The error message mentioned about "Invalid argument" of mount, anything > > > wrong? > > > So the problem now is why can not mount the drive even it's detected? > > > > It can detect the drive, but it doesn't find the i partition.

Re: NFS mounted but shows nothing even df -h has it
You made the point, thank you Maksim.

So the problem now is why can not mount the drive even it's detected?

NFS mounted but shows nothing even df -h has it
Hello, I have OpenBSD 7.2 installed and NFS service running on Cubieboard2, one Linux client and one MacOS client, everything works fine for the last 6 months. Yesterday as usual I mounted NFS share and showed mounting successfully even command `df -h` got it, but `ls /Users/jazzi/nfs` showed nothing. Tried on both Linux and MacOS. OpenBSD is 24*7 running and I didn't do anything to change the system, maybe it's too hot so I shut it down for the whole night and power on the next day but it didn't work. +++ Here is how I mount it on MacOS: > sudo mount -t nfs -o > resvport,async,nolocks,locallocks,soft,wsize=32768,rsize=32768 > 192.168.31.231:/mnt/hdd /Users/jazzi/nfs +++ Here is the settings on OpenBSD NFS server: # $ cat /etc/exports # For Macbook Air /mnt/hdd -alldirs -mapall=root 192.168.31.76 # For Linux desktop /mnt/hdd -alldirs -mapall=root 192.168.31.77 Any help will be appreciated, thank you. -- jazzi Best Regard,
