-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 hi I noticed this as well when trying to download an image of sonar linux from a fedora live environment. The download would get part way through, usually around 20-21 percent, then fail. I thought it was my network connection, but afterwards nothing else worked. Applications wouldn't launch, bits of gnome would fail to work, etc. This explains it. I was actually worried this was a general linux issue, but if it's a fedora one it's probably a simple fix Thanks Kendell Sent from Sonar GNU/Linux Moez Roy wrote: > On Thu, Apr 16, 2015 at 4:13 PM, Moez Roy <moez.roy@xxxxxxxxx> > wrote: >> Copying more than 500 MB crashes Fedora Live CD even though there >> is sufficient RAM. >> >> It doesn't matter how much RAM your system has, once you copy >> more than 500 MB you will get stuff like "Input/output error" or >> just plain crashes like "Segmentation fault". >> >> Why does this happen? > > I think I figured out why this happens. > > The file > /usr/lib/dracut/modules.d/90dmsquash-live/dmsquash-live-root.sh > seems to create a 500MB overlay: > > dd if=/dev/null of=/overlay bs=1024 count=1 seek=$((512*1024)) 2> > /dev/null if [ -n "$setup" -a -n "$readonly_overlay" ]; then > RO_OVERLAY_LOOPDEV=$( losetup -f ) losetup $RO_OVERLAY_LOOPDEV > /overlay else losetup $OVERLAY_LOOPDEV /overlay fi fi > > Wouldn't it be more efficient if this was tmpfs instead? > > This also affects installing applications in the live environment > where the installed size is more than 500MB. > -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCgAGBQJVMcNMAAoJEGYgJ5/kqBTd7fYP/3HKS7d43SyUAujcZ9cogUfY BALgSCsHvLp5YO3vL7GuSwqCcBEKyliXOTZNFiZRmgWYmYYO87xNTuHizfEj4yhI fHg2Efu48UITXzpBCYLKLg5DMJqOue9d13fD7qzr5E9Oqrzwhkcp60TCDAo5MIGn Y0v+T8LdpQ2+INJMnFGq+F8ucQTSqcBpYpJQbAnSIE1svVT+dg+7erc/I0sd98mh wcOmDO1+rZCsK/muL/LEJtWv6lSXzkVMgVCTMBD2/zzLIcYDiUHg0I0pwCQrF510 WzhktMjuUsOTN1t9H+k9V92LQIzgH8Lxxu6D1VBjdDA5uy7e7H2qblyLRO/erIL/ pPXzsgUqTw3rxx0HaNDnTbE/Bf4mFg80t54pzdKphhRAYp4uxyd6jX5AjFZagStZ 9bMURX/LLSy64JvWfbbLPiCUS5HeDuZwdInCFsDKb9zcwfjwNYrD435l0qqNOyCl sKRUjyGyAvrYxhF4WBJh36t5Di5M8wPVeutePb0jLDA1A3PZgK8WJUVsw0Z+tBfu BoT+5SISJdfUWfQE0pkq8QjWgFXZKhvCyXoHwfByDeaXknhR4G4kzQ39XQBdB8gU VZrIqX6aG+YYO6bSovJn9bwdtTE4XJqyglPPAK0zffFKVqZBx5Q6z5n04Ija6/Vu vV45pbZPdpr1cW0K3Ksm =TNuR -----END PGP SIGNATURE----- -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
