fighting the lack of good ideas
I recently discovered an interesting “feature” of symbolic links in conjunction with NFS mounts: they don’t work! For example, let’s say you have the following NFS export: /media/files Inside of that export, you have the following path: /media/files/isos/osmedia/linux/ubuntu In *this* directory, you have a symlink called ‘current‘, which points to a different location: current ->…
Most typically in the past, I have seen mounts for CDs in RHEL work thusly: mount /dev/hdc /mnt In RHEL6 you need to do the following: mount /dev/sr0 /mnt I’d really like to know why Red Hat made the change, but knowing is useful 🙂
Came across this little gem recently: /path/to/vmware-tools-distrib/vmware-install.pl –default EULA_AGREED=yes That’s been a life saver a lot recently 🙂
Last time I talked about storage robustifiers. In the context of a couple applications with which I am familiar, I want to discuss ways to approach balancing storage types and allocations. Storage Overview Core requirements of any modern server, from a storage standpoint, are the following: RAM swap Base OS storage OS/application log storage Application…
In part 2, I introduced SAN/NAS devices, and in part 1, I looked as the more basic storage type, DAS. Today we’ll look at redundancy and bundling/clustering of storage as a start of a robust storage approach. Before I go any further, please note I am not a “storage admin” – I have a pretty broad…
Continuing my series on storage strategies and options (see part 1), today I want to briefly look at SAN and NAS options. First, storage area networks. SANs are “dedicated network[s] that provides access to consolidated, block level data storage”. Storage presented to a target server appears to the machine as if it is a “real”…
In follow-up to my previous article about bind mounts, here is the first in a series on storage strategies (while everything contained in this series is applicable to desktops and laptops, the main thrust will be towards servers). Today we’ll look at local/simple storage options (DAS – both the spinning and solid-state varieties). The most…
