Thanks, the patch works for me (we're usually not using acl, and that's what I've checked). Yair. On Sun, Jan 22 2017, sf...@users.sourceforge.net wrote: > Hello Yair, > > Yair Yarom: >> We're also seeing this issue, where removexattr returns EINVAL. Our ro >> branc

Re: aufs 4.9 removexattr issue

2017-01-22 Thread Yair Yarom
We're also seeing this issue, where removexattr returns EINVAL. Our ro branch is nfs (without acl), and rw branch is tmpfs (without xattr). Mounting with noacl or with +icex doesn't help. On kernel 4.8 it worked fine. Simply mv'ing a directory from ext4 to the aufs will complain: $ mv /tmp/aaa

aufsed /etc + sungrid = Oops

Hi, We have here diskless machines with aufsed /etc (rw tmpfs /etc_rw + ro root /etc on /etc). When trying to run sungrid's qmaster daemon, we get an oops. Without the aufsed /etc there's no oops (even when there are other aufsed directories). The kernel is 2.6.33.3 with aufs standalone from

Hi, Thanks, I was hoping to avoid this since it tends to be one of the things you forget to remove or forget they are there during an update (but my other solution was to mount /sbin using aufs :)). Thanks, Yair. sf...@users.sourceforge.net writes: Hi, David: Why don't you just write
