I don't understand why you don't just fix your application to handle a
perfectly valid and expected condition (that it's currently not
handling) instead of wasting time trying to find the cause of the
expected condition. Even if you find it, it's likely not a bug and not
something that can/will
Hi.
I think it would help if you knew what the signal was. Do you have that
yet?
I have a report from a user that is is getting EINTR when a SIGALRM goes
off on his write(). It isn't unexpected to get SIGALRM because he
called the alarm, but he also has SA_RESTART set. I can't remember

Dear list members,
We are using Lustre 1.8.5 (upgraded from 1.8.4) running on 1 MGS, 3 OSS over
DDR IB, and 2 patched clients mounted with the flock option.
We are experiencing issues with an application that gets a EINTR when trying to
write to a file.
Those errors happens randomly on both

If I understand that errno properly, that is to be expected.

No, but not handling it properly is. Interpreting an EINTR as the disk
must be full (i.e. a fatal error) is wrong.

OK, the app is used to deal with standard disks, that is why it is not
handling the EINTR signal propoerly.
I think you're misunderstanding what a signal is in the Unix sense.
EINTR isn't a signal; it's a return code from the write() system call
that says, Hey, you got a signal in the middle of

As for your questions :
- I have to mention that I always had had this issue, and this is why
I've upgraded from 1.8.4 to 1.8.5, hoping this would solve it.
Ah, okay, I misunderstood that; my apologies.
- I will try to have that SA_RESTART flag set in the app... if I can

Hello
Hi,
From my understanding, Lustre can return EINTR for some I/O error cases.
I think that should/would be an EIO.
I think that when a client gets evicted in the middle of one of its RPC,
it can returns EINTR to the caller.
