Re: [lustre-discuss] root squash config not working anymore
Good morning, Jane- I want to say when my group has had this problem, the most reliable fix has been to unmount the MDT, lustre_rmmod, remount the MDT, and conf_param again (which unfortunately, as you no doubt recognize, results in a brief, but significant, interruption in availability). -Laura ___ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
[lustre-discuss] root squash config not working anymore
Hi, We are facing an issue with root squash in our Lustre file system. It used to work perfectly, but recently, it stopped taking effect. I've been trying to have root access on our MDS server to access the Lustre file system, but none of the configurations I've tried seem to work anymore. Here are the settings I've tried so far: (1) mdt.myfs01-MDT.root_squash=0:0 (2) mdt.myfs01-MDT.nosquash_nids=20.42.34.79@tcp mdt.myfs01-MDT.root_squash=99:99 (3) mdt.myfs01-MDT.root_squash=0:0 mdt.myfs01-MDT.nosquash_nids=20.42.34.79@tcp Despite all these attempts, I still face a 'Permission denied' error when trying to create a regular file in lustre using root account. Here is an example: [root@myfsmds01 /]# mount -t lustre 20.42.34.79@tcp:/myfs01 /mnt/ [root@myfsmds01 /]# lctl get_param mdt.*.*squa* mdt.myfs01-MDT.nosquash_nids=20.42.34.79@tcp mdt.myfs01-MDT.root_squash=0:0 [root@myfsmds01 /]# cd /mnt [root@myfsmds01 mnt]# mv /tmp/aaa /tmp/test.dat [root@myfsmds01 mnt]# cp /tmp/test.dat ./test18 cp: cannot create regular file './test18': Permission denied [root@myfsmds01 mnt]# sestatus SELinux status: disabled This issue started recently, and I haven't made any significant changes to the system. Are there any known problems with root squash that I might have missed? Thanks in advance, Jane ___ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
