Hi! Today I tested again whether ecryptfs would be suitable to replace encfs on my laptop. But I found several problems. The blocking one is: ms@merkaba:~/Training/TXS-svn/Linux_15_Performance_Tuning#2> LANG=C make […] sed: couldn't open temporary file ./sedhqlAcd: Permission denied […] ms@merkaba:~/Training/TXS-svn/Linux_15_Performance_Tuning> LANG=C ls -l | tail -6 ls: cannot access sedhqlAcd: No such file or directory ls: cannot access sedChky0a: No such file or directory ls: cannot access sed1eW8Ek: No such file or directory ls: cannot access sedEjR2oA: No such file or directory ls: cannot access sedb4JEiI: No such file or directory ls: cannot access sedy0KQnt: No such file or directory -????????? ? ? ? ? ? sedChky0a -????????? ? ? ? ? ? sedEjR2oA ---------- 1 ms teamix 1143445 Dec 5 10:01 sedNL1bTk -????????? ? ? ? ? ? sedb4JEiI -????????? ? ? ? ? ? sedhqlAcd -????????? ? ? ? ? ? sedy0KQnt Output in dmesg is: ms@merkaba:~/Training/TXS-svn/Linux_15_Performance_Tuning> sudo tail -2 /var/log/syslog Dec 19 13:23:30 merkaba kernel: [50999.570071] ecryptfs_write_metadata: Error writing metadata out to lower file; rc = [-13] Dec 19 13:23:30 merkaba kernel: [50999.570083] Error writing headers; rc = [-13] Ecryptfs is configured as follows: merkaba:~> cat .ecryptfsrc ecryptfs_unlink_sigs ecryptfs_sig=[…] ecryptfs_fnek_sig=[…] ecryptfs_xattr ecryptfs_key_bytes=32 ecryptfs_cipher=aes ecryptfs_passthrough=n I am using extended attributes to avoid the space waste of 8 KiB per file.
