I am trying to ensure that certain files in a mounted filesystem are readable to at least one non-root user. However, at the moment, even root user is not able to read these files. Here is my situation:
Here is the relevant line in fstab:
sshfs#andrew.eisenberg@marykate:/ /mnt/marykate fuse defaults,uid=1000,gid=1000,idmap=user,allow_other,follow_symlinks 0 0
(Note that andrew.eisenberg user is already a member of the groups fuse, redis, and david)
On the marykate machine, here is the directory in question:
[13:48] marykate:~
$ ll /var/lib/redis/7000
total 1089640
-rw-rw---- 1 redis 671476509 Jun 15 13:48 appendonly.aof
-rw-rw---- 1 redis 444305035 Jun 15 13:47 dump.rdb
On the target machine, it looks like this:
[13:46] ashley:/mnt/marykate/var/lib/redis/7000
$ ll
total 1091116
-rw-rw---- 1 david 672465989 Jun 15 13:49 appendonly.aof
-rw-rw---- 1 david 444831971 Jun 15 13:49 dump.rdb
And there are no users who can actually access these files:
$ sudo less appendonly.aof
appendonly.aof: Permission denied
$ sudo -u david less appendonly.aof
appendonly.aof: Permission denied
I think the reason why the files are owned by a different user is because the uids of the two machines don't match up.
However, I am completely confused why I am not able to read these files.
I am quite new to this and am just stumbling around, so any other advice on what I should do would be appreciated.
EDIT I have a workaround, but I am not happy with it. In the mounted filesystems, I have changed all the relevant files to be readable by all. And now on the base file system, I am able to read them all.
I do not like this solution since I do not want to make these files world readable. I would prefer to keep them user/group readable only, but don't know how.
