Temperature on Poweredge 2850
by Surya Saha 18 Oct '12

18 Oct '12

I am trying to get the temperature of a Poweredge 2850 with CentOS 6.3 on it. Has anybody on this list done this successfully? Thanks -Surya PS: Apologies for cross posting if you are on the Poweredge list. -- Surya Saha Department of Plant Pathology and Plant-Microbe Biology Cornell University, NY, USA http://www.linkedin.com/in/suryasaha

Linux Software RAID 1 - Unequal Sized Hard Disks
by Manish Kathuria 18 Oct '12

18 Oct '12

Has anyone created or rebuilt a Linux Software RAID having mirrored partitions on unequal sized hard disks ? There is a CentOS 5 server having two 400 GB hard disks with five mirrored partitions (software RAID 1) and one of the hard disks is dying. Since new 400 GB HDDs are not available here, we are exploring the possibility of replacing the faulty hard disk with one of a higher capacity (500 GB or more). And once it is fully replicated, we plan to replace the other 400 GB HDD also with another hard disk of the same higher capacity. Just want to know if anyone has done something similar and what are the chances of success (or data loss) ? Thanks, -- Manish

Debugging I/O Errors that abort the journal
by james 18 Oct '12

18 Oct '12

I got a I/O error on one of my disks that caused the journal to abort (error below) and be mounted in read only mode. I rebooted and the file system check ran automatically and resolved the error. I did some searching around and couldn't find a likely cause (the disk is a virtual disk, shared from a SAN for VMWare ESXi5.0). An hour after bringing the system back up, we got another one. Same sort of error, different inode. Went to run level 1, and ran fsck manually (running now). I don't see any obvious errors in the vmware-log file for the VM. Or on the SAN. All the other VMs are running fine and I don't see any issues there. Is there a good process to follow when trying to debug an I/O error like this? There are so many variables in this case. Wasn't sure if there were any ext3 utilities that I don't know about but should be using Error: Oct 18 02:52:38 shiva clamd[3978]: SelfCheck: Database status OK.

Remember Linux Soft RAID is for partitions not disks, then, you need to create the new partitions on the bigger drive at the same size of the old ones. Then replicate. When you had changed the two drives you can create a new soft RAID partition on the space leaved. But, if you are already planning on change the two disks. You can mount a new RAID1 schema using the new drives and then copy the data to the new disks. As for guarentee the safest of the data, first backup :D Antonio. -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Antonio S.

I've had two 64 core R815's for two months and have had no problems with them running CentOS 6.3. Just remember that these are bulldozer's and that for each processor of "16" cores, there are 16 integer cores and 8 shared floating point cores. I would love to get my hands on the sandy bridge r620s with idrac7. Ryan Thank you for the feedback. I also have 6.3 running smoothly on a 2850 > (up till now). I don't expect any major issues with R815's but just > checking in case somebody found otherwise. > > -Surya > > -- > Surya Saha > Department of Plant Pathology > and Plant-Microbe Biology > Cornell University, NY, USA > http://www.linkedin.com/in/suryasaha

centos 5 and php53
by John R Pierce 17 Oct '12

17 Oct '12

so whats the scoop on PHP53 for CentOS 5? I have a long running webserver, runs a bunch of mostly php+postgresql stuff, mostly hobby sites (clubs and local scout troops and such). has latest updates to php 5.2.10-xx but I want to install something thats insisting on php53. If I try and yum install php53, it says it conflicts with php-5.2.10 ... ok, do I remove the old PHP and install the one one? does that stand a reasonable chance of not blowing up in my face? -- john r pierce N 37, W 122 santa cruz ca mid-left coast

Rsync - include only files containing matching string
by Sean Carolan 17 Oct '12

I have a string, "2012_10_16"; let's call this $YESTERDAY How can I rsync a file tree from a remote machine to the local one, including *only* filenames that contain the matching string? I've read the man page and googled around but can't seem to get the syntax right. I either end up syncing all the files, or none of them. Here's how the code looks now (I will remove the dry run once it is working): rsync -avz --dry-run --include=*$YESTERDAY* remotehost:remotedir/ localdir/transfer/
