Top Forums UNIX for Advanced & Expert Users Root and non-root user not able to delete the file Post 302780631 by verdepollo on Thursday 14th of March 2013 08:42:54 PM

Aside form the most common "issues" like a partition being explicitly mounted read-only or a faulty disk array, there's been a widely known bug in RHEL 5 -more specifically in its kernel- where a filesystem might go read-only with no apparent reason.

It has been extensively documented (and fixed) both by RedHat and by VMWare as it mostly affects RHEL servers running under a hypervisor:

https://bugzilla.redhat.com/show_bug.cgi?id=494927
VMware KB: Linux based file systems become read-only

Either upgrade your kernel to a newer version or use the quick and dirty (and temporary) approach of rebooting the machine.

...of course not before trying mount -o remount <your_filesystem>

URI::URL(3pm)						User Contributed Perl Documentation					     URI::URL(3pm)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
