CentOS 7, xfs
by m.roth＠5-cent.us 25 Sep '14

25 Sep '14

Well, I've set up one of our new JetStors. xfs took *seconds* to put a filesystem on it. We're talking what df -h shows as 66TB. (Pardon me, my mind just SEGV'd on that statement....) Using bonnie++, I found that a) GPT and partitioning gave was insignificantly different than creating an xfs filesystem on a raw disk. I'm more comfortable with the partition, though. b) There was a small but significant difference if, when I created the filesystem, if I gave sw and su in the mkfs.xfs command. I do have a question for the group mind, though: mounting these monstrous partitions... should I, or, in fact, do I *need* to give, as a mount option inode64? There will be a *lot* of files on this sucker.... What are the pros and cons of that? mark

daemon for nfs client
by Dan Hyatt 25 Sep '14

25 Sep '14

In days of old, in Solaris there was a daemon for NFS Client, and NFS server (actually several including portmap...). I am unable to find reference to the daemon that runs NFS client But the RedHat Documentation does not explain the NFS client daemon. Is this a service or something else. on centos6.5 I previously posted about a really weird root filesystem. It started on another non critical server. so I found out when I unmounted the NFS filesystem the problem went away. BUT the NFS filesystem will not remount. On the non critical server, an old windows trick "reboot fixes everything" brought NFS and the mount up clean no problems But I want to try and fix this on the critical server without a reboot. Is there a way to stop and start the NFS client like I can restart the NFS server?

LS command bizzare behavior
by Dan Hyatt 25 Sep '14

25 Sep '14

Hi, My bosses are running into an issue, where we type "ls" on a nfs mounted filesystem, and files that are there are not listed... I thought it was pilot error until my big boss showed me... but we can vi the files, we can access them via other means if we know the name. Then once we have accessed them, LS now shows the files. We are running centos 6.5, we are accessing them via xwin-32 (which should not be the issue).... I looked on google and found nothing discussing this...of course this has nothing to do with hidden files (dot in front) because once we access the files we can see them. Thanks Dan

launching samba and having logs
by Mihamina Rakotomandimby 25 Sep '14

25 Sep '14

Hi all, I try to setup a Samba/Openchange service. In the Oopenchange documentation, they advise to launch samba in an interactive mode and a verbose level: I like that. http://www.openchange.org/cookbook/configuring.html # samba -d3 -i -M single The problem is I want to launch it via an init script (centos6) # .... SMBDOPTIONS=" -d3 -M single " # .... start() { echo -n $"Starting Samba services: " daemon samba $SMBDOPTIONS RETVAL=$? echo [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$SAMBA_NAME || \ RETVAL=1 return $RETVAL } # ... I dont get the same verbose output in any log file in "/var/log/samba/" How to get the same verbosity in a log file when launching samba from an init script? BTW, I dont understand what is the difference between /var/log/samba4/log.samba and /var/log/samba4/log.smbd Thank you very much.

C7 - implementation guide URL?
by Dave Stevens 24 Sep '14

24 Sep '14

I went to the RH site and used wget to download an offline copy for some work I'm doing. When I went back I had a gig of text and no end in sight. This was due to multiple (a lot) languages. I tried downloading the English version only but it seems there are links somehow that lead every time to other languages. Does anyone have a URL for a downloadable implementation guide for English only? TIA Dave

They're doing it as emx, where x=[1...], except where it wants old Sun-style pxdx... which I hate. I can live with emx, if I have to. People who can't count from 0.... Folks here heard about the actual fork of systemd called uselessd? And they want it to do actual work, but not much of what systemd does...? mark "saw it on slashdot"

semi-OT: hardware RAID and xfs on CentOS 7
by m.roth＠5-cent.us 24 Sep '14

24 Sep '14

Hi, folks, I'm about to build a filesystem on a CentOS 7 box, on a JetStore RAID box through a QLogic ISP2532 card. Do I need to specifiy sw and su, or will xfs query the subsystem and get that itself? mark (assuming nixpam lets me through....)

Centos 7 + SystemD + Predictable Network Interface Names
by Alessandro Baggi 24 Sep '14

24 Sep '14

Hi list, I'm trying Centos7 and using systemD. I've noticed that interfaces name does not have anymore eth0,eth1, ethN but a different name. What do you think about predictable network if name assigned by systemd?
