...-tuning/linux/ Did you try to enable readahead (blockdev ?setra) on the filesystem? On the client side, changing the mount options helps. The default read/write block size is quite little, increase it (rsize, wsize), and use noatime.

Dear all, When I create a share with the "admin users" permission (see smb.conf) and map a drive to it from win2k, it does not allow me to: Edit files Create files Remove files Add Directories Remove Directories Each time it gives me a permissions error. And I ever tried adding user1 to the UNIX group that maps to the Windows Domain Admins group: net groupmap modify

Hi, I need some help with NFSv4 setup/tuning. I have a dedicated nfs server (2 x E5-2620? 8cores/16 threads each, 64GB RAM, 1x10Gb ethernet and 16x 8TB HDD) used by two servers and a small cluster (400 cores). All the servers are running CentOS 7, the cluster is running CentOS6. Time to time on the server I get: ?kernel: NFSD: client xxx.xxx.xxx.xxx testing state ID with incorrect

...k. For Solaris, quota can be set when mounting from NFS client. There is a transition from Solaris to CentOS 6 this time. Therefore, quota setting is required for NFS mounting from CentOS 6 as with Solaris. Is it still impossible for CentOS 6? koji On Sun, 2 Apr 2017 14:44:59 +0200 Patrick B??gou <Patrick.Begou at legi.grenoble-inp.fr> wrote: > Quota are managed at the filesystem level, so they are managed by the > NFS server. > rquotad allow NFS clients to display users quotas when the filesystem is > mounted. > Be carefull withe autofs, if a remote filesystem is no...

Hi, I have a strange problem with my centos7 file server. I have a large data storage (75TB in RAID6, managed by lvm) and each night I create a snapshot? (removing first the previous one). The snapshot is mounted read-only so if a user remove a file accidentally he can restore it in the same day. However, if this snapshot exists, reboot of the server freeze at boot time and I must manually remove

Hi, I have a setup problem with cups on my CentOS7 laptop. In client.conf If have set the cups server FDQN used at work ServerName servprint.lmy.lab.fr But when I'm at home if I do not comment this line with: # ServerName servprint.lmy.lab.fr cups freeze as soon as I try to print something on my local home printer as the remote server is unreachable. This seams to be an old 2012 bug
