[solved] Ext4 goes read-only after nodealloc

Hello.
I've been trying this many times, but never succeed with using my partitions powered by ext4 file system with nodealloc option in fstab. It doesn't matter, if I add this option after defaults or replace defaults with nodealloc only. After reboot, all ext4 partitions (/ and /home) goes read-only, so I can't do anything with Arch, not even change fstab back. There are no problems, if I put other options to fstab (for example: relatime to ext3 file systems).
Anyone have same problem?

Whoa! That explains everything. I will try one more time.
EDIT: Yeah, this is it. It's nodelalloc, not nodealloc...
Thanks

System goes read only, after reboot all is fine for a day or two

OK, so here's the problem, I got a new PC, all fanless, SSD hard and all.
Works well for a day or so, then goes read only. For example - I come back from work, type something in the terminal and I get Input/Output Error. I cannot reboot, it says Input/Output Error as well.
So I hard-reset it, it boots up, everything is fine again for a day or two.
The HDD is Corsair CSSD-F40GB2, the MB is Gigabyte H55N-USB3, proc i3 540,
The / and /home are both ext4 mounted with defaults,noatime,discard.
I tried with/without discard.
I also tried changing the SATA/power cables - same results.
I also tried enabling/disabling features in BIOS like DMA/SMART/AHCI/compatibility stuff - same results.
Here's a dmesg I managed to get (errors are near the end).
http://pastebin.com/vJfdW90z
And here's a smartctl -a /dev/sda:
http://pastebin.com/eQxASEBM
Any suggestions are welcome. Also is there some diagnostic app for Corsair SSD that I can run and check the drive?
Cheers.

Well I don't recall how freshly booted, it was the only time that the system was read-only - giving input/output error to everything but dmesg was working so I saved it all to pastebin.
The system is a PC so I never tried anything else different from poweroff/reboot (works fine).

[SOLVED]root partition read only after update systemd

After update systemd today, the systemd-remount-fs.service fail to start. Root filesystem is read only I tried add rw to fstab mount option, but the root parition is still read only. I noticed that util-linux package are installed and udev package is dropped , Does it related to my problem?
Please advice me.
Sorry for my bad English.
Update
After downgard util-linux package, the system work again
Update 2
UUID in grub.conf and fstab are inconsistent, Thanks to tomegun for point out this problem.

External drive goes read only with error -50 after time

Running the special release of 10.8.2 for Mac Mini (2012) that was recently released. I have two external USB drives. The first contains my iTunes collection and the second is my time machine backup disk. The iTunes drive seems to go read only after it's been mounted awhile. I can read files off the drive, but I can't make any changes. I can't delete files nor edit them.
If I try to do anything with the disk including a repair permissions or disk on it, I get an error -50. The only way to get out of this state is to unmount the drive and remount it forcibly or reboot.
Anyone have ideas on what is going on or experienced a similar issue?

I did a little more research and there are quite a few people who've seen this error. I don't think it's the drive.
I suspect the controller in the enclosure, a jmicron 0x2336, is responsible for my problems. It looks like Linux and FreeBSD both had software updates to work around bugs in the controller. If OS X did not get updated, it would explain everything. The drive sleeps and then won't wake up fully and OS X marks it as in error and goes read only.
The enclosure is a Thermaltake Silver II USB + esata. It looks like a lot of people have had similar problems with them. I saw posts on macrumors, adobe's support forums, etc.

How to make fields read only after form is filled in

I am creating forms to be used within our company. The customer srv representative (CSR) would fill in the form and send it to the customer for signature and initial. There are a few issues I can't solve.
1) I need to make the rate & services fields read only after the CSR initials the form

Will the CSR have Acrobat or just Reader, and what type of computer will the CSR be using (Windows/Mac/mobile OS)? If just Reader (Wind/Mac), this is possible by setting the fields to read-only with JavaScript. The problem is this can't be considered secure, even if using a password as discussed here: Password-protect and hide one form field
With Acrobat you have the ability to flatten certain fields, which makes it a bit more difficult to change the "fields".

Forms going read-only in Workbench

Has anyone else had a problem with forms going read-only unexpectedly in Workbench ES? With no one else logged-in to the server, I'm experiencing intermittent errors where the current form I am working on suddenly thinks it is a read-only document and refuses to allow me to save it back into the repository.
Any suggestions as to how to resolve this would be appreciated.

Try to create a new connection from Workbench to the server and give it another name.
This might solve your problem.

Filesystem goes read-only

Hi, all
Yesterday, OVM Server3.1.1 was crashed. due to ovspoolfs.img was corrupted. I recovered ovspoolfs.img.(but OVM Manager didn't recognize that server.)
Main problem is that Filesystem goes read-only. I checked out /var/log/messages. but There are no disk errors or I/O erros.
Does anyone know what could be causing this problem or any solutions?
Thank you for your help.

Thanks for all these great tips!
As R00KIE pointed out I don't have a good backup system. I think I will go to my computer shop next monday to fix some good backup drive, because this quite scared me actually.
As for now I acted as follows:
Reboot, try to remount /srv and /opt [they are on the same disk].
Result: Bulks of errors. Lots of "soft resetting link" and "link to slow".
Another reboot, which kicked me in single user mode. I was had to remount / and was able to alter /etc/fstab, so that /srv and /opt were not mounted by default.
Shutdown system, open the casing.
Clean internals with vacuum cleaner. Unplug all harddisk cables and plug them back again.
Fire up the system. Mount /srv.
Try to make backup of important data on /srv.
This seemed to work, and there are no errors anymore. Probably some cable was loose, somehow. But I still do not really trust the situation, and will fix some backup routine.
Thanks again for all the tips and tricks. I will definitely run some extra checks and utilities from now on!
jocom
P. S.: Running "e2fsck -f -y -v" on both /srv and /opt says everything is fine. No errors, no bad blocks.

Make a field required on record creation, read only after that

Hello,
Does anyone know of a way to make a pick-list field required on record creation, but read-only after that? The other twist to this is that we need to allow this field to also be read-write for all the integration edits, since this field's value could change in the enterprise database.
Thanks,
Neal G.

Hi !
I think you can add a validation rule for that. Something like :
IIf(PRE('<YOURFIELD>') IS NULL, <> '', = PRE('<YOURFIELD>'))
This means that if the previous value of your field is null (it's a creation), so the value must be different than blank. Else, it must be equal to the previous value, so not modified.
I didn't tested it, but I let you get back to me if it works... or not !
You'll just have to add a message saying that this field is required on creation and readonly after...
Hope this will help, feel free to ask more !

RAID Goes Read-Only (-50 Error)

I have a first-revision xserve raid, connected via a Vixel 335 to 4 servers, zoned so there are two on each RAID controller, with LUN masking allowing one volume to appear on each server.
One pair of servers tends to break each other whenever something happens. I restart one server and the other one stops being able to write to the xserve raid. Any write attempt results in a -50 error. Then if I restart the one that went bad, it breaks the other the same way. If I restart them at the same time, it usually works, but sometimes does not, sometimes the volumes won't even mount. RAID admin loggs a "Fiber LIP" when either server restarts. That seems normal, but it why does the RAID stop allowing writes on the other volume? Anyone seen anything like this before?
This pair of servers are second-revision G4 xserves with the pre-installed FC cards.
Thanks for any input.

Word 2010 document becomes Read-Only after saving it

Hi,
My Word 2010 document is becoming "Read Only" after saving it, for information my doucment is on the desktop . I searched on this forum and find a couple of solutions (deactivating auto saving, etc.) but it does not work at all. Any other ideas?
Thanks,
Sylvain.

, I wonder why the docuemnt is becoming Read-Only when I am saving it on the Desktop...
I've read articles and blogs of people arguing each side of whether you should use the Desktop as a storage folder and I really
don't have anything substantial to add to either the pro or con side of the issue.
However, what I know about Word is that it behaves a bit different and seems to have issues when you’re actively editing document that are stored
on the Desktop. I would speculate that the issue has something to do with the screen driver software.
When you’re editing a document, Word is actually using something like a dozen or more temporary hidden files and some of these are stored in the
same folder as the source document. If the source document’s folder is the Desktop, then there has to be interaction with the screen driver.
This interaction with the screen driver is one variable that makes the Desktop folder unique and possibly problematic and thus Word under certain conditions
makes the file Read Only.

Changing a Record to Read-Only after an event.

I have a Developer application that needs to be modified. This
application includes several fields as well as a comments
field. I'd like to change all updatable fields (not to included
the comments field) to READ-ONLY after a certain event. Then
after a certain date, I'd like to make the comments field READ-
ONLY.
Do you have any suggestions?

Dear Regina,
Have you tried to set_block_property in pre-record trigger to update allowed/not allowed depending on the event. And in post-record update not allowed. These triggers must be on block level. Also on item level to the item 'Comment' define pre-item trigger where take a new decision whether you want to open the entire block or not, the same way as on block level triggers. But in post-item trigger always make the entire block read-only again.

Make all text fields read only after signing form

Hello,
I have a live cycle form which needs to have all of the text fields set as read only after signing.
The java script has been placed in the post sign event of a digital signature field.
for(var i=0;i<this.numFields;i++) {
var cNm = this.getNthFieldName(i);
if (cNm.type = "text") this.getField(cNm).readonly = true;
After signing the form the following console error is shown:
this.getNthFieldName is not a function
Can anyone please advise how to revise the script so that when the form is signed all of the text fields become ready only?
Any assistance will be most appreciated.
Thank you.

You don't need any JavaScript to do this.
In Designer you can setup the signature field in that way, that all fields will be locked after signing.

Firefox profile folder becomes read-only after closing browser

firefox profile folder becomes read-only after closing browser
It is a problem with firefox or is it this to to a virus?
How to fix? How to prevent?

Only a check mark in the Read-only box means that a folder or file is Read-only.<br />
Windows doesn't check all the files in a folder so instead displays a greenish block to indicate that it is not sure.<br />
You need to look at the files individually to see if any are read-only.<br />
Easiest to do that is to make the Attributes visible in "View > Details" mode: Choose Details in Windows Explorer.<br />
