Hello Everyone, We are using CentOS 5 system for certain application. Those are VM guests running in VMware. There is datastore issue occasionally, causing all file systems becoming read only file systems. So application stop working, and opened files cannot be written either. We cannot even ssh login to the system. Typically we had to power cycle the VM. We are trying to add reliability to the

Hi, I am recovering a CentOS 5.4 system. I've copied all partitions into the recovery system. I've installed grub boot loader. However, the original system is using /dev/sdb1 for root (/), while the recovery system is using LVM (/dev/vg0/lv1) for root (/). When recovery system boots, I got the panic error: * Mounting /dev/sdb1 on /sysroot * Mount: mounting

Dear All, Below question has been puzzled me for a while, and don?t know if anyone has experienced such puzzle: You have an external array attached to a physical hardware. The operating system is CentOS 5. The file system is created on top of LVM on external array & mounted. The CentOS 5 can see the array controller, and manage all LVM configuration, etc. There is data stored in that

Hello All, I guess it is very common for administrative purpose, to dump and restore a CentOS 7 system. I usually use dump/restore commands. However, I?m having trouble to handle installing bootloader and creating initramfs for C7 system. Does anyone know a good document source that details those procedure? Thank you, Xinhuan Zheng

HI all- Thanks for the comments. However -I'm getting no where. Let me start again. My 'hardware" does not have the ability to turn off secure boot. Its an Intel NUC7C - not possible. SO instead of my generic "image" i have that I copy to physical disk (has all my install,setup etc... everything ready). I created a new UEFI disk that again has everything setup and ready.

Hello, Thanks for all feedback I got. I am pretty sure that if I used ?openssl enc? method, it is able to handle large file over 250g size perfectly. I think openssl installed on the system is capable of doing large file support. However, when using ?openssl smime?, it is not able to. Apparently it?s smime method limitations, not the openssl. Other than smime and enc, what other methods can I use

Hi All, I have a Quantum scalar i40 tape library. I need to configure it to TWO tape partition libraries, e.g., library_a and library_b, so that each library has its own tape drive. Then connect this physical tape library to two different CentOS servers so that each server can see its own media changer and tape drive. I once had a successful configuration on one host but NOT on the other. One

I use a solution to crypt a string that I found using OpenSSL. But the crypted string becomes very long, too long for a varchar 255 to hold it. What can I do to make it shorter? Or should I just use text as column in the mysql db? public_key_file = ''lib/public.pem'' public_key = OpenSSL::PKey::RSA.new(File.read(public_key_file)) @encrypted_string =

Hi, all. So, in reviewing my OpenSSH keypairs and evaluating the size my RSA keys should be, i realized that, if i update my 2048-bit keypairs to 4096 bits, it really doesn't matter that much, because they're still only encrypted with 3DES, which provides an effective 112 bits of symmetric encryption strength: $ head -4 ~/.ssh/id_rsa -----BEGIN RSA PRIVATE KEY----- Proc-Type:

I would rather work on single files or tars on directory basis. Using a single big file creates a very "large" single point of failure. Or use an encrypted file system (of course, also a single point of failure, but probably better handling). Kai

I'm very interested in seeing support for stack/context switching in LLVM, if only for prototyping language ideas. I'm particularly interested in mechanisms that would make it possible to implement full asymmetric coroutines as described in "Revisiting Coroutines" (Moura & Ierusalimschy, Feb 2009 TOPLAS). From skimming the thread and looking at the llvm-stack-switch wiki, it

Hello list, Sorry, these questions are not directly linked to R. If I consider an indefinte real matrix, I would like to know if the symmetry of the matrix is sufficient to say that their eigenvectors are real ? And what is the conditions to ensure that eigenvectors are real in the case of an asymmetric matrix (if some conditions exist)? Thanks in Advance, St?phane DRAY
