Hi all, I'm new to LDAP and want to use nss_ldap (version 253) against a centos directory server (version 8.1.0) running on the same host. The great mystery is, that as root everything works find, but as any other local user, it does not: root$ getent passwd [...] ldap:x:55:55:LDAP User:/var/lib/ldap:/bin/false ns:*:4000:4000:Nicolai Stange:/home/ns:/bin/bash root$ su some_local_user -

...need guaranteed-complete filesystem-level snapshots, you need to be using something at the kernel level that can atomically collect the set of modified blocks/files, rather than something that crawls the tree in user space. Generally, I agree with you. In fact: https://bitbucket.org/gordonmessmer/dragonsdawn-snapshot https://github.com/rsnapshot/rsnapshot/pull/44 Doing block-level differentials is nice, if you're using ZFS. But not everyone wants to run ZFS on Linux. I do think that backing up snapshots is important, though.

Hi all! I'm still on C6. I'm using a RAID1 configuration (Linux software RAID) and I'd like to either use the same one, or possibly configure it on new drives (larger) when I upgrade to C7. (I'm really feeling the need to move off C6.) But it isn't at all obvious how one would do a new RAID1 setup in Anaconda, and I don't find any user reports or other info on this in the

I'm working on infrastructure to make that more common and more consistent: https://bitbucket.org/gordonmessmer/dragonsdawn-snapshot If you're interested in testing or development (or even advocacy), I'd love to have more people contributing. > That also avoids the access-time churn (for backup programs that > don't know O_NOATIME, like any that use rsync). Yes, though rsync based systems are usual...

...ather than rolling your own.? Bacula has snapshot support.? Alternately, my project can manage snapshots and handle freezing / thawing PostgreSQL services.? I think it's a better option than Bacula's, but either is better than reinventing this wheel. https://bitbucket.org/gordonmessmer/dragonsdawn-snapshot

Will this be very slow if Alessandro has a large number of files? OTOH if he really needs to ensure integrity there likely isn't a better option. --keith -- kkeller at

Greetings - I am a novice system administrator and will soon be purchasing a new server to replacing an aging file server for my company. I am considering setting up the new server as a KVM host with two guests; one guest as the Samba file server and a second guest as a testing area. My old server was set up about 7 years ago and has a 5 disk raid 5 configuration without LVM. I understand

I've used LVM on servers with hot-swap drives to migrate to new storage without downtime a number of times. Add new drives to the system, configure RAID (software or

FFS, don't do the latter. LVM is the standard filesystem backing for Red Hat and CentOS systems, and fully supports consistent snapshots without doing half-ass shit like breaking a RAID
