[PATCH] e2fsck: exit journal recovery when jounral superblock fails to update
by Zhiqiang Liu 30 Jan '22

30 Jan '22

Jounral superblock may be failed to update in e2fsck_journal_release. But if needs_recovery flag is cleared, e2fsck_check_ext3_journal will be failed. To fix this case, we use "fatal_error" when recover journal failed. So we can reserve the recovery flag to recover the journal when try e2fsck again.

[PATCH] e2fsck: add env param E2FS_UNRELIABLE_IO to fix unreliable io case
by Zhiqiang Liu 30 Jan '22

30 Jan '22

Func write_primary_superblock() has two way to wirte disk. One is 1k block, the other is byte by byte as default. On unreliable IO case such as flaky network, the byte-by-byte method may lost some data of ext4-superblock. Then, the superblock may lose consistency and the sb checksum error will occur. We provide the env param E2FS_UNRELIABLE_IO for users to choose if it's necessary to take 1k block way on writing disk.

[PATCH] e2fsck: exit journal recovery when find EIO, ENOMEM errors
by Zhiqiang Liu 30 Jan '22

30 Jan '22

jbd2_journal_revocer() may fail when some error occers such as ENOMEM. However, jsb->s_start is still cleared by func e2fsck_journal_release(). This may break consistency between metadata and data in disk. Sometimes, failure in jbd2_journal_revocer() is temporary but retry e2fsck will skip the journal recovery when the temporary problem is fixed. To fix this case, we use "fatal_error" instead "goto errout" when recover journal failed. If journal recovery fails, we will send error message to user and reserve the recovery flags to recover the journal when try e2fsck again.

glusterfs 22.03-LTS删除子包说明
by haowenchao 29 Jan '22

29 Jan '22

Hi All: 软件包glusterfs升级到10.0版本引入两个子包（glusterfs-ganesha和glusterfs-regression），这两个子包依赖的rpm在openeuler中没有提供，导致子包无法正常使用，将会删除这两个子包。 glusterfs-regression是回归测试用的子包；glusterfs-ganesha 是基于NFS-Ganesh提供使用glusterfs作为NFS服务端的功能， openeuler没有提供NFS-Ganesh，故glusterfs-ganesha也无法使用。如果有人使用到了上述子包，请在https://gitee.com/src-openeuler/glusterfs提issue跟踪讨论。

[DISCUSS][DB] Collect and Discuss whether reserve the mentioned DB software/libraries in the following openEuler 22.03
by bo zhaobo 29 Jan '22

29 Jan '22

Hi guys, I'm from DB SIG, currently, everyone in openEuler is busying in the development. And we also face some questions need to be clear, so we want to collect some ideas from openEuler community, customers and users. We are difficult to judge whether we should still reserve the following DB related software/library in openEuler 22.03 LTS. So we consider to make them vote in public ,direct us to make the decision according to the requests we will get. Note that the mentioned ones are in openEuler 20.03 LTS, you guys need to leave your comment(request) in the issue( https://gitee.com/openeuler/community/issues/I4SGDD?from=project-issue) We will leverage our work based on the issue comments. 1. greenplum(6.17.0) 2. postgresql(10.5)/postgresql-13(13.3) 3. neo4j (4.3.0) 4. tidb (4.0.14) Note that "issue comment format", please leave which ones you still need and request summarized content there.
