I maintain a ubuntu 20.04 LTS headless server and I can manually mount the B2 bucket using fuse s3fs for backup. How to add a line to fstab to automatically mount the B2 bucket at powerup? I know that altering fstab can be tricky. The mount script I have obtained from Backblaze [FAQ](https://help.backblaze.com/hc/en-us/articles/360047773653-Using-S3FS-with-B2) : > sudo s3fs \ > mybucket \ > /path/to/mountpoint \ > -o passwd_file=/etc/passwd-s3fs \ > -o url=https://s3.your-region.backblazeb2.com

How to search for a string inside a lot of .gz files in Amazon S3 bucket subfolder? I tried to mount it via s3fs and zgrep but it's sooooo slow. Do you use any other methods? Maybe is there any Amazon service which I could use to quickly zgrep them?

Does the mv command (temporary) duplicate the moved files when the target is an S3FS mount? I have a VM that is reaching total space consumption. So, I'd like to move some files to a storage bucket (**mounted using S3FS**) to free up some space. Since I'm currently using 88.7% of 28.90GB, which is approximately 25.70GB and the directory I plan to move is 8.2GB, I'm afraid to use 100% and get stuck.

-shell
mv /path/sourcefolder/* /path/destinationfolder/

I downloaded and installed [s3fs 1.73](https://code.google.com/p/s3fs/wiki/FuseOverAmazon) on my Debian Wheezy system. The specific steps I took were, all as root: apt-get -u install build-essential libfuse-dev fuse-utils libcurl4-openssl-dev libxml2-dev mime-support ./configure --prefix=/usr/local make make install The installation went well and I proceeded to create a file /usr/local/etc/passwd-s3fs with my credentials copied from past notes (I'm pretty sure those are correct). That file is mode 0600 owner 0:0. Piecing together from the example on the web page and the man page, I then try a simple mount as a proof of concept to make sure everything works: $ sudo -i # s3fs mybucketname /mnt -o url=https://s3.amazonaws.com -o passwd_file=/usr/local/etc/passwd-s3fs In short: it doesn't. The mount point exists with reasonable permissions, and I get no error output from s3fs. However, nothing gets mounted on /mnt, mount has no idea about anything of the sort, and if I try umount it says about the directory "not mounted". The system logs say s3fs: ###curlCode: 51 msg: SSL peer certificate or SSH remote key was not OK, but **how do I find out which SSL certificate it is talking about or in what way was it not OK?** Firefox has no complaints when I connect to that URL but also redirects me to https://aws.amazon.com/s3/ . **How do I get s3fs to actually work?**

Using S3FS, a specific folder in a bucket can be mounted using s3fs bucket:/path/to/folder . This works fine for me. I'd like to mount in the same way using an entry in /etc/fstab, but can't figure out how to specify the path to the folder. Mounting the entire bucket works just fine: bucket local_path fuse.s3fs _netdev,allow_other,passwd_file=/etc/password-s3fs 0 0 However, specifying the folder path results in the bucket being unrecognized: bucket:/folder local_path fuse.s3fs _netdev,allow_other,passwd_file=/etc/password-s3fs 0 0 s3fs_check_service(3711): bucket not found - result of checking service. Is there a different way of specifying a path to a folder?

I am using Fedora 23 and I have autofs set to automount some s3fs FUSE filesystems when directories under /mnt/s3 are accessed. Since I set this up, I always experience an additional delay upon logging in - from looking at journalctl, it looks like something is immediately activating one of those s3fs filesystems as soon as I login - but this fails and times out because the wireless network connection is not yet up. How can I find out what is causing this unwanted mounting, and/or disable it?

I am installing s3fs-fuse on Ubuntu 14.04 ( Bitnami - EC2). Actually I want to mount S3 bucket.
I installed the required dependencies successfully by running following command

apt-get install build-essential libfuse-dev libcurl4-openssl-dev libxml2-dev mime-support automake libtool

Rest of the procedure mentioned as below

cd /tmp
wget https://github.com/s3fs-fuse/s3fs-fuse/archive/v1.77.tar.gz 
mv v1.77.tar.gz s3fs-fuse-1.77.tar.gz
tar zxvf s3fs-fuse-1.77.tar.gz
cd s3fs-fuse-1.77/
./autogen.sh
./configure --prefix=/usr
make
make install

while "make" (2nd last step) i am getting for following error

I have an s3 share that's mounted via s3fs-fuse and would like to run some speed tests to compare throughput on DreamHost's DreamObjects vs Amazon S3. Everything is mounted and working just fine (s3fs testbucket ~/mnt/test -o passwd_file=/path/to/passwd-s3fs -o url=http://objects-us-west-1.dream.io), but traditional tests like dd and hdparm just don't work out. Any recommendations on running a successful speed test on a block storage device in such a scenario?

I'm looking to set up a common directory which is writable via SFTP by a certain set of users. This set of users should be able to access only this directory, and only via SFTP. I have successfully set this up, using the following sshd configuration: Subsystem sftp internal-sftp Match Group sftponly ChrootDirectory /mnt/filebucket ForceCommand internal-sftp AllowTcpForwarding no PermitTunnel no X11Forwarding no PasswordAuthentication yes # temporary for testing My users are part of the sftponly group, and they can log in and they are successfully chrooted into the directory. The catch, though, is that I want to mount an S3 bucket (using s3fs) in this /mnt/filebucket directory. Once I mount it, the permissions on the directory change from drwxr-xr-x 2 root root (sshd approves for chroot) to drwxrwxrwx 1 root root (sshd does *not* approve). Is there something about how I'm mounting this directory that is causing this issue?

The Fuse packages that are available by default on CentOS 7.3 are a bit dated. The compilation process for Fuse 3 and s3fs should be pretty straight forward. Fuse compiles and installs fine: mkdir ~/src && cd src # Most recent version: https://github.com/libfuse/libfuse/releases wget https://github.com/libfuse/libfuse/releases/download/fuse-3.0.0/fuse-3.0.0.tar.gz tar xvf fuse-3.0.0.tar.gz && cd fuse-3.0.0 ./configure --prefix=/usr make make install export PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/lib64 ldconfig modprobe fuse pkg-config –modversion fuse No problems there... Things show up where they should it seems, $ ls /usr/lib: > libfuse3.a > libfuse3.la > libfuse3.so > libfuse3.so.3 > libfuse3.so.3.0.0 > pkgconfig > udev $ ls /usr/local/lib/pkgconfig/: > fuse3.pc $ which fusermount3: > /usr/bin/fusermount3 So I proceed to install s3fs: cd ~/src git clone https://github.com/s3fs-fuse/s3fs-fuse.git cd s3fs-fuse ./autogen.sh ./configure --prefix=/usr And then every time, I hit this: ... configure: error: Package requirements (fuse >= 2.8.4 libcurl >= 7.0 libxml-2.0 >= 2.6) were not met: No package 'fuse' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables common_lib_checking_CFLAGS and common_lib_checking_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. Any idea why s3fs is not finding Fuse properly?

This is my incrontab line: /srv/www IN_MODIFY,IN_ATTRIB,IN_CREATE,IN_DELETE,IN_CLOSE_WRITE,IN_MOVE rsync --quiet --recursive --links --hard-links --perms --acls --xattrs --owner --group --delete --force /var/www_s3/ /var/www /var/www_s3/ is an s3fs mount. However, it only gets kicked off when a file is modified manually; nothing happens when a file is changed/added on S3. Is there a way to get incrontab to detect these changes?
