I'm pulling my hair out trying to setup a mirrored logical volume. lvconvert tells me I don't have enough free space, even though I have hundreds of gigabytes free on both physical volumes. Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data Insufficient suitable allocatable extents for logical volume : 10240 more required Any ideas? Thanks!, Gordon Here's the output from the

Hi list, I'm building a NFS server on top of CentOS 8. It has 8 x 8 TB HDDs and 2 x 500GB SSDs. The spinning drives are in a RAID-6 array. They are 4K sector size. The SSDs are in RAID-1 array and with a 512bytes sector size. I want to use the SSDs as a cache using dm-cache. So here what I've done so far: /dev/sdb ==> SSD raid1 array /dev/sdd ==> spinning raid6 array I've

hi guys, gals do you know if conversion from lvm's raid10 to raid0 is possible? I'm fiddling with --splitmirrors but it gets me nowhere. On "takeover" subject man pages says: "..between striped/raid0 and raid10."" but no details, nowhere I could find documentation, nor a howto. many thanks, L.

Basic tar question: I have created a ar file with tar -prvf /tmp/ib_backup.tar /opt/interbase/data/* The file has been copied to another box and I want to untar the file into /opt/interbase/data/ I am not sure about the syntax; how to specify where I want the data to be placed. Here is my start of the command: tar -xvf /tmp/ib_backup.tar #The tar file is in /tmp Todd --

I want to be able to recompile php, so I downloaded the src dvd and did a rpm -i php-4.3.9-3.15.src.rpm After doing that I wanted to check to see if I can recompile it before making changes. So, I went to the SPECS dir and did a rpmbuild -i php.spec It spent a lot of time doing the compile, but at the end there were errors. What am I missing? Todd -- Ariste Software 2200 D Street Ext

My version of Centos (4.4) comes with php 4.3.9. Since I run Interbase on the server, I need to recompile the php with Interbase. The only php I have found is 4.4 which I have downloaded and untarred as well as configuring it with Interbase, doing the make and make install. Where I am lost is on having Apache (httpd) use it rather than the 4.3.9 ( http://209.204.172.137:82/testphp.php ).

Dear Friends, I am new to Linux and Wine. I have just d/l wine and trying to configure it. I would like to know that after loading wine on Linux can i get windows like start button and menu ? I want to install Interbase Client on wine. It has normal windows style setup program i.e. setup.exe file. Can somebody tell me how to use setup programs with wine and later use them ? Thanks R. S.

http://209.204.172.137:82/testphp.php So, I will need to recompile PHP with MySQL (and Interbase), however I do not want to "upset the appple cart" by bring in something that will cause conflicts. Is there a step-by-step discussion on how to do this for php 4.3.9? Todd -- Ariste Software 200 D Street Ext Petaluma, CA 94952 (707) 773-4523

I'm experimenting with using WinXP Xen guests as an alternative to upgrading workstations. The administrative advantages seem overwhelming. Please share thoughts about using VNC vs RDP for remote desktop connections. Please share any anecdotal information regarding user reactions and/or implementation issues.

I use named virtual hosts on my web servers, as I'm sure many others do. I'm used to the method of using a vhost directory for the container files. I didn't find documentation for it in the CentOS docs or the Apache docs. I'm not sure if I should take it as a hint that it is depreciated... If I've missed something, please point me to it. I've written a quick

Evening folks: Not sure where this fits into the picture so bear with me for a few moments while I think out loud to lay out the particulars of my problem. -would love to be employed using R for a living but so far I have just worked with it on my home machine to develop a basic level of skill with it. -I run Ubuntu linux 8.04 LTS on a machine with a 2.5GHz Celeron processor and 1.2GB of memory.

Dear R-fans, My database access package RODBC is now available on CRAN. For those who have never used it, odbc is a database and platform independant API which provides an SQL interface to a large number of database engines. The databases supported include not only SQL based RDBMS but also CSV files, foxbase, dBase, MSExcel etc. ODBC has been promoted mainly by Microsoft and this is where the
