I have the following fs:

/dev/sdb1            exfat     60085120    11776  60073344   1% /mnt/apuntes

in the /etc/exports:

/mnt/apuntes 192.168.2.20(rw,sync,no_subtree_check)

the service is started and I launch the following command:

exportfs -ar

and I get the following error:

exportfs: /mnt/apuntes does not support NFS export

Can't export in exfat format ??? what am I doing wrong

nfs fuse nfs4 exfat

Here is an /etc/fstab record example of one of the mounts as per x-systemd.automount and other goodies:

UUID=XXXX-XXXX /media/XXXX-XXXX auto noauto,nofail,nouser,uid=root,gid=users,umask=007,X-mount.mkdir,x-systemd.automount,x-systemd.device-timeout=1,x-systemd.idle-timeout=60 0 2

Currently this external exFAT-formatted drive is physically disconnected from the PC, but I still get the following surprises

$ ls /media
ls: cannot access '/media/XXXX-XXXX': No such device

and

$ findmnt /media/XXXX-XXXX
TARGET           SOURCE    FSTYPE OPTIONS
/media/XXXX-XXXX systemd-1 autofs rw,relatime,fd=55,pgrp=1,timeout=60,minproto=5,maxproto=5,direct,pipe_ino=24590

This obviously fools other software, which might potentially be using findmnt to determine whether the mount is up, to believe that the storage drive is actually mounted and to proceed with further actions.

How do I make sure that when the drive is physically disconnected, it is no longer considered by the Linux system?

My SystemRescueCD (bootable CD based on Arch Linux distribution) won't mount my exFAT SD card. When I plug in the USB reader, /dev/sdc appears, but it won't even show /dev/sdc1. No way to mount it, mount /dev/sdc1 /mnt/1 will fail.

It is interesting that /dev/sdc1 is recognized by cfdisk /dev/sdc - it shows that there is a free space of ~ 1 MB and then the /dev/sdc1 of ~ 64 GB. But there is no /dev/sdc1 appearing on the filesystem! If I put normal FAT SD card in the reader, the /dev/sdc1 appears correctly.

How do I make SystemRescueCD mount exFAT? Looking in /root/packages-list.txt, it contains exfat-utils 1.3.0-1. I was able to run mount.exfat and mount.exfat-fuse, but still there is the problem that /dev/sdc1 doesn't exist, and trying to mount /dev/sdc obviously results in an error.

It is rather surprising, that SystemRescueCD isn't able to do this by default, the purpose of "rescue CD" implies to me that it should be able to mount as many filesystems as possible).

(I have SystemRescueCD version 6.0.3, uname -a gives Linux sysresccd 4.19.34-1-lts #1 SMP Sat Apr 6 19:41:19 CEST 2019 x86_64 GNU/Linux; it doesn't seem that this issue would be different in the newest version)

I have a git-daemon accessed through ssh. All repositories are in /srv/git.

I have some other projects saved on a exfat disk, so I want to create a symbolic link from that disk to /srv/git.

For example, I have /mnt/Medias/Projects/Defi\ H.git so I simply do:

cd /srv/git
sudo ln -s /mnt/Medias/Projects/Defi\ H.git

But the file is created as root:root, 777.

To restrict access to the repositories, I want to change the posix rights of that file. If first try:

sudo chmod 755 Defi\ H.git
chmod: changing permissions of `Defi H.git': Function not implemented

I've found that this is because the link points to a folder stored on an exfat disk. In the same way, this fails:

sudo chown git:defih Defi\ H.git
chown: changing ownership of `Defi H.git': Function not implemented

So I want to create the link as the right user directly:

sudo -u git -g defih ln -s /mnt/Medias/Projects/Defi\ H.git
Sorry, user geoffroy is not allowed to execute '/bin/ln -s /mnt/Medias/Projects/Defi H.git' as git:defih on Aethelflaed.

I'm part of group wheel and sudo's configuration shows:

%wheel ALL=(ALL) ALL

I don't understand why this last command fail? Any advice?

Or am I supposed to make a copy of the file on another filesystem? /srv/git is btrfs, if this have any importance.

The operating system is Windows Server 2003 R2 x64 with all updates applied.

I have an external hard disk enclosure (one of these) with a 1 TB drive (garden-variety Seagate). When I right-click in Explorer and choose “Format…” the only option is exFAT. I really want NTFS.

  • If I do try to format as exFAT, I get a generic error message: “Windows was unable to complete the format.”
  • Other external drives give me a choice of NTFS or exFAT.
  • Problem occurs over both USB or Firewire.

Workaround: I was able to use diskmgmt.msc to format as NTFS.

But I am wondering:

  • Why wouldn’t Explorer offer NTFS as an option? Is this a red flag for problems?
  • If NTFS is not a formatting option in Explorer, should I do anything with the disk? Re-partition?
