hi list, i have a little problem with 2-node RAC using OCFS. the application running on this cluster does heavily index-based accesses. the data volumes are SAN volumes connected by fibrechannel. the throughput does not exceed 10mb/s, average is 7-8 mb/s. i've used 'iostat -x' and got rkB/s=8000 while %util=100% (device was saturated) from kernel's POV. i did some

SYSTEM: rh6x based system, 2.2.19-6.2.7 rh errata kernel + 0.0.7a patch, I rebuilt rpm for i686; celeron466, 64MB, PIIX4. root fs is on software raid1 ext2, 6 additional fs's on software raid1 ext2. There's a 3rd HD, not mirrored, which is mounted ext3. EXT3-fs: mounted filesystem with ordered data mode. I enabled journal with tune2fs -j with unmounted fs. The 3 HDs are tuned with

Hello list First of all: Good work and thanks for GlusterFS! I'm totally new to GlusterFS, but i like it a lot and think about migrating my NFS setup completely to GlusterFS. But i ran into some problems with my chosen structure. Hopefully someone can help out. The first questions: i ran into some performance issues with a certain structure/setup and like to know (before i continue testing)

I have a file Server CentOS 5.10, its on the internet, so I compress all csv into one file using (tar -czvf compressed_files.tar.gz *.csv) on this server so that I can download them as one compressed file to save bandwidth, Disk space on this server available is 50Gig, so when I copy the files onto Redhat EL 5.9 and decompress them using (tar -zxvf *.gz) It decompresses maybe 80% then get error:

I'm running samba 2.2.3a-6 under Debian (testing) and I am having a heck of a time getting Windows 2000 to print to my printer. I keep getting that "Access denied, unable to connect" message. At one point I had it so you could print test pages, but as soon as you tried to print from an application, it would break. However, that doesn't even work anymore. I've been reading

Hi all, Any ideas, why is this happening or how to debug this? After random time (usually one to three days uptime) inode-sz reported by sar jumps way up its normal level and <24 hours after this bug has happened server will crash. Server used to work fine, but started to do this around beginning of June. --- 08:20:00 AM dentunusd file-sz %file-sz inode-sz super-sz %super-sz

Hello I am starting testing with dovecot 2.0.9. In my //etc/dovecot/dovecot.conf/ I have the following line: /mail_location = mdbox:/mydomain.org/%2.26Hn/%2.200Hn/%n:INDEX=/mydomain.org/indexes/%2.26Hn/%2.200Hn/%n/ These are my questions (a long mail): *1? How should I restore from backup with mdbox & separate indexes?* I have read in dovecot list archive about restoring the full

I just installed this new version of SAMBA 2.05b on a HPUX 11.0 v-class system. Has anyone seen this error before and possibly set me in the correct direction?

I have two variables, both numerical. I would like to find the unique values of the pairs, in other words, unique coordinates if I were to plot them. I also need to know how many pairs there are, but I guess I can use length() if I can somehow isolate the unique pairs first? Thanks a lot! Bonnie Yuan

anyone having, had, or even have any thoughts on the issue described below? its killing me.... The short description of the problem is: using direct to server UNC type paths, we see 'normal' speeds. Going threw a DFS (re)director, we see very bad performance from any machine running 3.0.*, but not 2.2.3a. We make heavy use of DFS. This service is on a machine named

I'm just wondering what folks are using to benchmark/tune large arrays these days. I've always used bonnie with file sizes 2-3 times physical RAM. Maybe there's a better way? Cheers,

Hie I lost my CentOS 7 root password, so I tried booting the OS in single user mode but it prompts me for the root password when the system boots, Any ideas? Regards Bonnie

I have a CentOS6.3 SAMBA file server. All the users are on a Windows Server 2008 Active Directory Domain Controller and authentication is done using Winbind integration on SAMBA . Everything works well except that if someone logs on to the Samba Server, they see all the shared folders there and also a folder with their own name %USER%. This Folder is not accessible, one cannot enter into this

Full_Name: Bonnie Version: 1.6.1 OS: Windows Submission from: (NULL) (160.129.25.106) glm() seems to converge, even when it shouldn't. I am trying to fit a model where $converge=FALSE and I am fitting models that do not converge in SAS, but they seem to converge in R ... Thank you.

I'm doing a text mining project where I have to manually enter a double quote as an element inside a vector. I tried char[10]='"'#where i enclosed the double quote in a pair of single quotes. But the result is [1] "\"". Somehow a back slash is added automatically. I also tried to enclose the double quote in a pair of double quotes. That didn't work either.

Hi Gang, I recently rented a server at a datacenter with Centos 5.7 X64, Q9550 Processor, 8GB Ram, and dual 250GB SATA HDs (with 16mb cache). They had loaded it with KVM, and installed a 30-day trial of Virtualizor as the front-end for KVM. I was so impressed with how fasts the guests ran that I want to build a few of these machines for myself. I just installed one: same Q9550 processor, 4GB

We (a small college with about 3000 active accounts) are currently in the process of moving from UW IMAP running on linux to dovecot running on a cluster of 3 or 4 new faster Linux machines. (Initially using perdition to split the load.) As we are building and designing the system, I'm attempting to take (or find) benchmarks everywhere I can in order to make informed decisions and so
