Environment: - CentOS 5.1, - Apache 2.2.3 - php 5.1.6 - phpMyAdmin 2.11.6 - MySQL 5.0.22 Brand new system, brand new installation of all the above products. All looks well, but when I try to connect to phpMyAdmin, I get an error: "Forbidden: You don't have permission to access /phpMyAdmin/ on this server". I'll forgo all the paths I followed trying to get this to work and cut

We run a third party application that creates an inordinate amount of subdirectories in a single directory. To speed up I/O, I wanted to set the T attribute on the directory that will hold the subdirectories. The "chattr +T /usr/local/lepus-bb/a-0607" command returns status 0, but when I verify the setting, the attribute isn't there: # lsattr -d /usr/local/lepus-bb/a-0607

I browsed the web and the archive, and apart from someone asking whether anyone else had rsync problems after installing OpenSSH 3.4, I came up empty. Can anyone point me in the right direction to debug this? I've got over 50 GB to keep in sync, and don't know of another elegant way to do it. Environment: source system = bb: - Linux version 2.4.7-10smp

I'm trying to install CentOS 5.2 on a Dell PE 1850 via the DRAC 4 card, with CentOS-5.2-i386-bin-1of6.iso mounted as virtual media. At the boot prompt, I hit <Enter>, which should start the graphical installation, but it starts off with a text installation. I am asked - whether I want to test the media, which I skip - what language I want to use - I select English - what keyboard I

Hello, I have a situation where I have numerous files with numerous hard links to each of them on an ext3 RHEL4.2 system. Some of these files are duplicates of the others. I would like to re-link all of the duplicates to point to a single inode. For instance if file1 has hardlinks link1 and link2, and file2 has hardlinks link3 and link4, I need to change it so that link1, link2 (these

The relavant part of Dovecot configuration: dotlock_use_excl = yes mail_nfs_storage = yes mail_nfs_index = yes

Hi guys I have met some troubles when I want to evaluate the glusterfs performance with small file workload. 1: What kind of benchmark should I use to test the small file operation ? As we all know, we can use iozone tools to test the large file operation, while for the sake of memory cache, if we testing small file operation with iozone, the result will not correct.

Does samba 3.0.23c not support the use of O_DIRECT? When I try to open an smbmount'd file using O_DIRECT, I get EINVAL. I am able to use O_DIRECT with no problems on a block device and nfs mounts, so I know the kernel supports it. samba: 3.0.23c kernel: 2.6.9-42.0.3.EL (32-bit) I am using the below code for my test. smb fails on open(2). #include <fcntl.h> #include

My application always needs to sync file data after writing. I don't want anything handing around in the kernel buffers. I am wondering what is the best method to accomplish this. 1. Do I use EXT2 and use fdatasync() or fsync()? 2. Do I use EXT2 and mount with the "sync" option? 3. Do I use EXT2 and use the O_DIRECT flag on open()? 4. Do I use EXT3 in full journaled mode,

Hi, I have a ZFS dataset that has sync writes disabled (setting sync=disabled) which means that it will only do async writes, and sync requests get converted to async writes. The ZFS dataset is hosted on a single Samsung 840 Pro 512GB SATA SSD. I have this same dataset served as a Samba share, using Proxmox VE 6. Samba version 4.9.5-Debian (Buster), protocol SMB3_11. Kernel version 5.0.15. To

OCFS Experts, Sorry if the questions below are naive, or were answered before, but here it goes. I have a potential client who at the moment having problems installing 10g RAC on RHEL 3.0 (2.4.21-20). They using (rather planning to use) OCFS for everything, including CRS files (OCR, voting). Questions: 1) They use custom kernel (modified by their security people). Do we support OCFS on the

Hi David, Thanks for your reply. > Hmm, so this "async" (sync=disabled?) ZFS tunable means that it > completely ignores O_SYNC and O_DIRECT and runs the entire workload in > RAM? I know nothing about ZFS, but that sounds like a mighty dangerous > setting for production deployments. Yes, you are correct - sync writes will flush to RAM, just like async, will stay in RAM for

I have a system with many processes writing to a common data file using pwrite. These processes are each writing to existing blocks in the file, not changing the file size, and the file has no holes. When the processes get going, they seem to bottleneck at log_wait_common (according to ps alnx). That is, one process is uninterruptible in log_wait_common, the rest are uninterruptible in down.

I'm sure there is a more general way to ask this question but how do you use the elements of a character vector as names of objects in an expression? For example, say you have: a = c(1,3,5,7) b = c(2,4,6,8) n=c("a","b") and you want to use the names a and b in a function (e.g. sum) sum(eval(as.name(n[1])),eval(as.name(n[2]))) works but what is a simpler way to
