have a centos 5.1 box but not sure if i have ext2 or ext3 on the drives? basically trying to disable the file system check if there's a hard boot, which i wouldn't risk if its ext2 but will do if its ext3.

Can you check which php files are running?
where does that come from? I know they use shell access but where is that info?
I suspect there is bad sector in the disk. How do i check it w/o turning the server offline?
View 3 Replies View RelatedWe used Red Hat with ext2 as our file system on an old server with 100k+ of image files in a single directory. This seemed to preform ok until we switched to FreeBSD using UFS. Now images load very slow. I have read that Ext2 uses and internal hash to speed lookups, while UFS does linear searches for lookups.
View 2 Replies View RelatedWe're considering deploying a large server that will have 8x 500GB drives in a RAID-10 config. I intend to use a 3ware 9650SE w/ BBU along with A/B power to each of the PSU's.
My question is... since this will return into a 2TB array/partition, in event of a crash (kernel panic, etc -- I expect a power outage will be very, very rare if at all) what do you guys think the fsck time would be? In my experience a RAID BBU significantly drops it, sometimes to the point of no manual fsck required, but in event of a manual fsck shouldn't the BBU be able to provide more consistent data (less errors) and therefore a much shorter fsck? Maybe just recovering the journal?
OS: Debian etch
partition type: EXT3
I was unziping from network 4gb file to my server and server crashed. When I got it back up partition has allocated 4gb of space, but there is no file I cannot reallocate it.
/dev/hda6 67G 63G 437M 100% /home
Like you can see above 4gb is allocated but it is not used, so what can i do?
what are peoples opinions on running ext3 in writeback journal mode when the filesystem resides on a BBU (battery backup unit) RAID array. The BBU retains data cached on the RAID card, but all the delayed writes from writeback mode may not even have gotten to the RAID card. Am I correct on that logic?
View 5 Replies View RelatedI wanted to mount a Usb portable drive of some data I have inside my Linux server and make them read on my Windows xp.
The drive has been formatted as ext3 and it just won't show in "my computer" inside Windows unless I reformat it again as ntfs.
The same turns around if if I format as ntfs, and i can't mount it under linux with the message "mount: unknown file system type 'ntfs'"
Our server with raid 10 has had a failed hdd (which was replaced) and a
corrupt ext3 filesystem.
The server is now booted with Knoppix but drives will not mount. All we are trying to at this point is salvage as much data as we can.
i have a problem with my server it wan't boot, i get the following error on /tmp
fsck.ext3 e2fsck_read_bitmaps illegal bitmap block
how can i fix?
kernel: EXT3-fs error (device loop0): ext3_lookup: unlinked inode 12286 in dir #2
kernel: EXT3-fs error (device loop0): ext3_journal_start_sb: Detected aborted journal
EXT3-fs error (device loop0): ext3_lookup: unlinked inode 12286 in dir #2
some errors I get on my dedicated server? I also got errors like these when I deleted inside a folder a large number of files and after running every time 'du' it shows kernel errors.

I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts

I'm running CSF on a Cpanel server and have questions about new features in CSF
Apache Check
Check Apache weak SSL/TLS Ciphers (SSLCipherSuite)
Results
Cipher list []. Due to weaknesses in the SSLv2 cipher you should disable SSLv2 in WHM > Apache Configuration > Global Configuration > SSLCipherSuite > Add -SSLv2 to SSLCipherSuite and/or remove +SSLv2. Do not forget to Save AND then Rebuild Configuration and Restart Apache, otherwise the changes will not take effect in httpd.conf
Can someone explain this in laymen terms? I know this is new in Cpanel. I'm already running Apache 2.2, PHP 5.2.9 with suPHP enabled and mod_security as well (these rules: [url]
Also, what exactly are these CSF checks?
Check csf PT_SKIP_HTTP option
This option disables checking of processes running under apache and can limit false-positives but may then miss running exploits
Check csf SAFECHAINUPDATE option
This option closes a window of opportunity that opens when dynamic chain updates occur

I finally nailed it down and came on a conclusion that my MaxClients were set too low so I had to set it to high number and it seems like that the proble of "Network Timeout" had been resolved but now the problem is still continued. Here is what I think is wrong
Cpu(s): 1.5%us, 0.4%sy, 0.0%ni, 96.7%id, 0.3%wa, 0.3%hi, 0.8%si, 0.0%st
