similar to: FS corruption? bogus i_mode

I have several CentOS5 hosts in a VMware ESX 3.5.0 226117 environment using iSCSI storage. Recently we've begun to experience journal aborts resulting in remounted-read-only filesystems as well as other filesystem issues - I can unmount a filesystem and force a check with "fsck -f" and occasionally find errors. I've found -

Hi, I'm running kernel 2.6.8-15, lvm2 v2.01.04-5 and acl v2.2.23-1 on a Sunblade 100 (sparc). In a few months we have experienced for several times that an ext3 filesystem is remounted as read-only (this is due to the option "errors=remount-ro" in /etc/fstab). Sometimes there is no error in log files but sometimes we see: kernel: init_special_inode: bogus i_mode (3016) kernel:

Hey, I've a problem with an ext3 filesystem and don't know how to fix it or find the failure :( The Hardware: Tyan mainboard, AMD Athlon CPU, ARECA ARC-1120 RaidController Raid5 with 400GB Seagate HD's, 756 MB Ram, other harddisks for system, network and avm isdn controller. Couse of the filesystem problems I run memtest and found one bad memory module which I replaced yet. The

The difference between kdev_t and dev_t in 2.4 is rather theoretical, no need to clutter up the source for it.

First let me confess that I am a R-novice. I am trying to fit a beta distribution for a dataset using fitdistr(MASS). I am having difficulties with it because the function tends to fit a distribution with a range of 0 to 1 (I guess). However, my dataset is not! Anytips or tricks will be very much appreciated. Many Thanks. T. S. Ramanarayanan, Ph.D. Aventis CropScience Research Triangle Park,

Hi, I am a newbie to llvm. I am wondering what approach is used when coming out of SSA form. I also appreciate pointers on where to look in the source code for this phase.

I am wondering how O4 vs O3 do inlining. With O4 it looks like inlining is done first on each file and then at linking phase. Wouldn't it be a better alternative to delay inlining decisions until the link stage? Ram -------------- next part -------------- An HTML attachment was scrubbed...

(sort-of xposted from linux-kernel) Hi, I am wondering how to interpret this error message, which popped up on a 2.4.26 SMP x86 box two days ago: EXT2-fs: corrupt root inode, run e2fsck init_special_inode: bogus imode (37316) EXT2-fs: corrupt root inode, run e2fsck init_special_inode: bogus imode (37316) EXT2-fs: corrupt root inode, run e2fsck The problem is, the error message doesn't

If -simd option is specified opt could do validity checks, dependency analysis and such and recognize that a loop can be executed in parallel and as the -simd option is specified, convert the data types to vector instructions and add the scaling factor to the loop's iterators. Following this there can be an early machine function pass that sets up processor specific value in all of

Hi, We are proposing a loop fusion pass that tries to proactive fuse loops across function call boundaries and arbitrary control flow. http://reviews.llvm.org/D7008 With this pass, we get 103 loop fusions in SPECCPU INT 2006 462.libquantum with rate performance improving close to 2.5X in x86 (results from AMD A10-6700). I took some liberties in patching up some of the code in

Yes in the sense that you may make some better

In reflink we update the id info in the disk but forget to update the corresponding information in the VFS inode. So update them accordingly in case we want to preserve the attributes.

When CONFIG_EXT3_FS_POSIX_ACL is not defined, ext3_init_acl() is an inline function in fs/ext3/acl.h which doesn't check if a file is a symlink before applying umask. I've always liked my acls to be available (so never noticed), but came across this recently when trying to explain why RedHat Enterprise 3's BOOT kernel creates symlinks 755 during kickstart. I'm *assuming* this is
